DESCRIPTION
Interpoint’s HUMMER™ Hold-Up Module Series provides a single
product solution to the problem of maintaining electronic system
operation during input power drop-out, typically reducing bulk
capacitance requirements by more than 80%. The HUMMER
module is compatible with the Interpoint DC/DC converters in
Section B1 that have a 28 VDC nominal input and a high input line
of 40 VDC.
GENERAL OPERATION
The HUMMER module and two external components (a hold-up
capacitor and a diode) are connected between the line source and
the DC/DC converter as shown in Figure 3 (HUMMER Module
System Block Diagram.) If an EMI filter is employed, the HUMMER
module is connected between the filter and the converter). The
module first charges the external capacitor to 40 volts, and then
allows the converter to operate off the line voltage. When the line
voltage drops to between 12 to 18 VDC, a boost converter in the
module supplies an output at the capacitor charging voltage (40
VDC). If power fails (the input voltage drops below 12 VDC), the
converter is powered from the external hold-up capacitor.
The traditional procedure for providing hold-up during power loss is
to buffer the device with enough bulk capacitance to allow a
controlled shutdown to occur or an alternative power source to be
brought on line. The problem with this approach is that very large
capacitor banks are required because the capacitors are charged at
the relatively low voltage at which power fails.
The HUMMER Hold-Up Module provides an alternative with two
important advantages: 1) it effectively reduces the low line voltage
for normal DC/DC converter operation to 12 VDC thereby reducing
power drop-out events, and 2) it charges hold-up capacitors to 40
volts, reducing the capacitance needed to produce a given hold-up
time.

Note: The HUMMER module is rated at a total operating power
more than its output rating in order to allow it to both deliver a
full load and to continue charging the external capacitor (the
HUM-40, for example, is rated at 40 W output and 60 W total
operating power, allowing it to deliver 40 W to a load and charge
a capacitor at 10 to 20 J/sec). However, if the input voltage
ramps up slowly into a full converter load, the total power drawn
at low voltage could send the module into current limit which
would shut the unit down.
DETAILED OPERATIONAL DESCRIPTION
The detailed operation of the HUMMER module is divided into 4
operations: Initialization and Charging, Normal Operation, Low
Line Operation, and Power Fail Operation. For details, refer to the
following text, Figure 4 (HUMMER Module Block Diagram) and
Figure 5 (HUMMER Module Signal Diagram).
1. INITIALIZATION AND CHARGING
As the input voltage ramps up to 8 to 10 volts, the internal
HUMMER module circuits are biased to provide correct output
states on all flags. As the input reaches 14 VDC, the Power Fail
flag (active low) is released, the voltage control switch (VCS) is
closed, and the module begins operating in a boost mode to
charge the external capacitor to 40 volts. At this point, if the recom-
mended connection has been made between the Capacitor
Charged pin and the inhibit pin of the converter as shown in Figure
3, all of the module energy is dedicated to charging the capacitor
and the converter will be inhibited until the capacitor charge
reaches 36 V. If this connection has not been made, the energy
available to charge the capacitor will be the difference between the
current required by the converter’s load and the current capacity of
the HUMMER module.
When the input voltage reaches approximately 22 VDC, the VCS
is opened, isolating the stored charge on the external capacitor
and allowing the converter to operate directly from the input power
bus via the external system diode (unless the converter is still
inhibited by the connection between the Capacitor Charged pin
and converter’s inhibit pin) while the capacitor continues to charge.
When the charge on the external capacitor reaches approximately
35 volts (80% of a full charge), the Capacitor Charged flag will be
asserted (removing the inhibit from the converter if applicable) and
the HUMMER module will be in normal operation.

2. NORMAL OPERATION
3. LOW LINE OPERATION
Normal operation continues with the capacitor charged and the
input line voltage between 18 and 40 VDC. During this time, the
converter will operate from the line voltage through the external
diode. When the external capacitor reaches its final charge of 40
volts, the HUMMER module enters an idle state, consuming only
enough power to keep the capacitor charged. Idle state power for
the module is approximately 1 watt.
Low line operation occurs when the input voltage drops to a range
between 18 and 12 volts. When the voltage reaches 18 VDC, the
HUMMER module’s VCS closes and then operates in a boost
mode. In this mode, the HUMMER module supplies 40 VDC
through VCS to the converter, and at the same time maintains the
charge on the capacitor. The module will operate indefinitely in this
low line region until the input line voltage drops below 12 VDC.
Note: The HUMMER module itself can sustain continuous voltages
of up to 50 VDC and voltage spikes of 80 volts for up to 50
msec, and it will pass these voltages on to the converter through
the external bypass diode. If these ratings exceed the rating of
the converter, care should be taken to control the line voltage to
prevent damage to the converter.
4. POWER FAIL OPERATION
When the input line voltage drops to 12 VDC, the Power Fail flag
is asserted (pulled low) and the HUMMER module’s boost mode is
disabled. At this point, the converter load is powered by the stored
energy in the external capacitor. When the voltage on the external
capacitor falls to 20 VDC, the Capacitor Charged flag is released
(pulled low), indicating that 90% of the usable stored energy has
been depleted. If the connection has been made between the
Capacitor Charged pin and the converter’s Inhibit pin, the
converter will also be inhibited.
Normal Operation will continue indefinitely until the input voltage
drops below 18 VDC.

PIN CONNECTIONS
CAUTION: Do not connect the HUMMER module’s input return pin
to the Cext return. This connection will short the module’s current
limit sense resistor resulting in excessive currents that can also
damage the DC/DC converter.
EXTERNAL CAPACITOR SELECTION
The external capacitor supplies the energy for the DC/DC
converter’s operation during power failure. Interpoint recommends
CLR-79 or CLR-81 wet slug tantalum capacitors because of their
high CV properties and extended temperature operation. An alter-
native choice is a high quality grade aluminum electrolytic. To
ensure maximum system stability, the capacitors should have a
minimum ESR of 0.25 ohms, a minimum capacitance of 330 uF, and
a maximum capacitance of 1 F.
INHIBIT FUNCTION
The HUMMER module’s inhibit pin disables the internal boost
converter when the Inhibit pin is pulled low. This is accomplished by
an external connection to the Vin Return pin or Vout Return pin. The
inhibit open circuit voltage is is 10 V and the short circuit current is
15 mA. It is open-collector TTL or CMOS compatible. The pin is
diode-isolated and can be reverse biased to include the input poten-
tial. Power Fail and Capacitor Charged flags are operable when the
unit is inhibited.
The capacitance needed and derating required will depend on the
system requirements, the load, and the efficiency of the converter
being supplied power. The amount of capacitance for a given hold-
up time is determined by the formula

The Power Fail Flag output is implemented by a comparator moni-
toring the input voltage. (The comparator is also used to inhibit
HUMMER module’s operation; note however, that the flag is func-
tional when the unit is inhibited.) The input voltage threshold is
nominally 14.5 V to indicate that sufficient voltage is present for
operation. The comparator output drives an internal MOSFET buffer
which connects to the external Power Fail pin. The buffer is of an
open drain configuration and requires an external pull-up resistor
and voltage for indication. The maximum recommended pull-up
voltage is 36 V. The maximum short circuit should not exceed 10mA.
The buffer is protected by a shunt zener diode connected between
the drain and the Cext Return. In normal operation, the input voltage
exceeds the 14 V threshold and the output is high (open drain).
When the input voltage is below 12 V the output is low, and the
MOSFET conducts to the Return.

CAPACITOR CHARGED FLAG
A Capacitor Charged Flag is implemented by a comparator moni-
toring the HUMMER module’s +Cext terminal. The capacitor voltage
threshold is 36 V, at which point the external capacitor is charged to
80% of its maximum value. When the capacitor discharges, the flag
resets at 20 VDC indicating that approximately 10% of the charge
remains. The comparator output drives a MOSFET buffer amplifier,
and the buffer output connects to the Cap Charged pin. The buffer
is of an open drain configuration and requires a pull-up resistor and
voltage for indication. The maximum recommended pull-up voltage
is 36 V. The maximum short circuit current should not exceed 10
mA. During normal operation, the input is 40 V, exceeding the
threshold, and the output is high (open circuit). When the capacitor
voltage is below 20 V, the output is low, and the MOSFET conducts
to the Return. The HUMMER module must be supplied with a
minimum of 8 VDC for biasing internal circuits to obtain correct
output states.
Note: The output power delivered by the HUMMER module to
deliver 30 W to the load with an 80% efficient converter is 37.5
watts. The HUM-40 is rated to deliver a maximum of 40 watts to
the input of the converter. Interpoint data sheets for individual
converters supply an efficiency curve vs. line and load for each
converter model. In calculations, assume the efficiency rating for
the nominal (usually 28 V) line condition.
Note: If the Capacitor Charged pin is connected to the converter’s
inhibit pin as shown in Figure 3, use 20 V as the low line figure in
the formula.
DIODE SELECTION AND CONNECTION
An external diode is required for system operation as shown in
Figure 3, with the diode anode connected to the HUMMER module’s
VCS pin and the DC/DC converter’s +V in pin. This diode supplies
input voltage to the converter when the internal voltage control
switch (VCS) is open. The diode should be selected with a minimum
current rating of 5 A and a voltage breakdown rating of 50 V or
greater (similar to Motorola MDR1060 or equivalent).
