90% Efficiency

Switching Regulators (ISRs) designed

to meet the on-board power conversion

needs of battery powered or other

equipment requiring high efficiency and

small size. This high performance ISR

family offers a unique combination of

features combining 90% typical effi-

ciency with open-collector on/off

control and adjustable output voltage.

Quiescent current in the shutdown

mode is typically less than 100µA.

Notes: (1) The PT6300 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.

(2) The ISR will operate to no load with reduced specifications.

(3) Input voltage cannot exceed 30V when the inhibit function is used.

(4) See Thermal Derating charts.

(5) Consult the related application note for guidance on adjusting the output voltage.

Application Notes

PT6100/6210/6300 Series

Adjusting the Output Voltage of Power Trends’

Wide Input Range Bus ISRs

Notes:

1. Use only a single 1% resistor in either the (R1) or R2

location. Place the resistor as close to the ISR as possible.

The output voltage of the Power Trends’ Wide Input

Range Series ISRs may be adjusted higher or lower than

the factory trimmed pre-set voltage with the addition of a

single external resistor. Table 1 accordingly gives the

allowable adjustment range for each model for either

series as V_a(min) and V_a(max).

2. Never connect capacitors from V_oadjust to either GND

or V_out. Any capacitance added to the V_oadjust pin will

affect the stability of the ISR.

3. Adjustments to the output voltage may place additional

limits on the maximum and minimum input voltage for

the part. The revised maximum and minimum input

voltage limits must comply with the following

Adjust Up:

An increase in the output voltage is obtained by

requirements. The limits are model dependant.

PT6100/6210/6300 Series

Using the Inhibit Function on Power Trends’

Wide Input Range Bus ISRs

Figure 1

V_in

For applications requiring output voltage On/Off control,

the 12pin ISR products incorporate an inhibit function.

The function has uses in areas such as battery conservation,

power-up sequencing, or any other application where the

regulated output from the module is required to be

switched off. The On/Off function is provided by the

Pin 1 (Inhibit) control.

The ISR functions normally with Pin 1 open-circuit,

providing a regulated output whenever a valid source

voltage is applied to V_in, (pins 2, 3, & 4). When a low-

level²ground signal is applied to Pin 1, the regulator

output will be disabled.

Inh

C O M

Figure 1 shows an application schematic, which details

the typical use of the Inhibit function. Note the discrete

transistor (Q1). The Inhibit control has its own internal

pull-up with a maximum open-circuit voltage of 8.3VDC.

Only devices with a true open-collector or open-drain

output can be used to control this pin. A discrete bipolar

transistor or MOSFET is recommended.

Turn-On Time: The output of the ISR is enabled automatically

when external power is applied to the input. TheInhibit control

pin is pulled high by its internal pull-up resistor. The ISR

produces a fully regulated output voltage within 1-msec of

either the release of the Inhibit control pin, or the application

of power. The actual turn-on time will vary with the input

voltage, output load, and the total amount of capacitance con-

nected to the output Using the circuit of Figure 1, Figure 2

shows the typical rise in output voltage for the PT6101

following the turn-off of Q1 at time t =0. The waveform was

measured with a 9Vdc input voltage, and 5-Ohm resistive load.

Equation 1 may be used to determine the approximate

current drawn by Q1 when the inhibit is active.

1. The Inhibit control logic is similar for all Power Trends’

modules, but the flexibility and threshold tolerances will be

different. For specific information on the inhibit function

of other ISR models, consult the applicable application

note.

2. Use only a true open-collector device (preferably a discrete

transistor) for the Inhibit input. Do Not use a pull-up

resistor, or drive the input directly from the output of a

TTL or other logic gate. To disable the output voltage,

the control pin should be pulled low to less than +1.5VDC.

maximum allowed input voltage is limited to +30Vdc.

t (milli-secs)

4. Do not control the Inhibit input with an external DC

voltage. This will lead to erratic operation of the ISR and

may over-stress the regulator.

5. Avoid capacitance greater than 500pF at the Inhibit control

pin. Excessive capacitance at this pin will cause the ISR to

produce a pulse on the output voltage bus at turn-on.

6. Keep the On/Off transition to less than 10µs. This

prevents erratic operation of the ISR, which can cause a

momentary high output voltage.

Eco Plan

-

The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS

&

no Sb/Br)

-

please check

http://www.ti.com/productcontent for the latest availability information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered

at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

(3)

MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder

temperature.
