NCV890430
0.6 A 2 MHz 100% Duty Cycle
Step‐Down Synchronous
Regulator for Automotive
The NCV890430 is a fixed-frequency Synchronous Buck regulator
intended for Automotive, battery-connected applications that operate
with up to a 45 V input supply. It is suitable for automotive systems
requiring low noise and low shutdown currents that also need to
operate at low input voltage close to the output voltage. A reset pin
(with adjustable delay) simplifies interfacing with a microcontroller.
This part also features an enable input that can either be connected to a
low voltage (such as a micro-controller output) or high voltage (such
as the battery input), and a synchronization input.

The NCV890430 also provides several protection features expected
in automotive power supply systems such as current limit, short circuit
protection, and thermal shutdown. In addition, the high switching
frequency produces low output voltage ripple even when using small
inductor values and all-ceramic input output filter capacitors −
forming a space-efficient switching regulator solution.

NCV890430
APPLICATION INFORMATION
General Description
because it reaches its maximum duty cycle, the high-side
MOSFET can turn on permanently (100% duty cycle
operation), to help lower the minimum voltage at which the
regulator loses regulation.
An overvoltage monitoring circuit automatically
terminates switching and disables the output if the input
voltage exceeds 37 V (see Figure 9), but the NCV890430
can withstand input voltages up to 45 V.
The NCV890430 is a high-frequency synchronous
switch-mode regulator with current-mode control, fixed
output voltage and fixed internal closed-loop compensation,
accepting a wide input voltage range typical to automotive
applications.
The use of a P-channel high-side MOSFET simplifies the
driving scheme (no bootstrap circuitry needed), and enables
a duty cycle of 100% for low dropout operation at low input
voltage.
To avoid skipping switching pulses and entering an
uncontrolled mode of operation, the switching frequency is
reduced by a factor of 2 when the input voltage exceeds the
Input Voltage
V
IN
Frequency Foldback threshold (see Figure 9 below).
An Undervoltage Lockout (UVLO) circuit monitors the
input, and can inhibit switching and reset the soft-start
circuit if there is insufficient voltage for proper regulation.
Depending on the output conditions (voltage option and
loading), the NCV890430 may lose regulation and run in
drop-out mode before reaching the UVLO threshold: refer
Frequency reduction is automatically terminated when the
input voltage drops back below the V Frequency Foldback
IN
threshold. This also helps to limit the power lost in switching
and generating the drive voltage for the Power Switches at
high input voltage. Above the frequency foldback threshold,
improved efficiency can be expected due to the lower
switching frequency.

Soft-Start
avoid sub-harmonic oscillations. The recommended
inductor value is between 1.8 and 3.3 mH, although other
values are possible.
Upon being enabled or released from a fault condition, a
soft-start circuit ramps the switching regulator error
amplifier reference voltage to the final value, forcing the
output to follow the same soft-start ramp. During soft-start,
the average switching frequency is lower until the output
voltage approaches regulation.
Short Circuit Protection
During severe output overloads or short circuits, the
NCV890430 automatically reduces its switching frequency.
This creates duty cycles small enough to limit the peak
current in the power components, while maintaining the
ability to automatically reestablish the output voltage if the
overload is removed.
In more severe short-circuit conditions where the inductor
current reaches the peak current limit during the minimum
on time, the regulator enters a hiccup mode that further
reduces the power dissipation and protects the system.
Slope Compensation
A fixed slope compensation signal is generated internally
and added to the sensed current to avoid increased output
voltage ripple due to bifurcation of inductor ripple current
at duty cycles above 50%. The fixed amplitude of the slope
compensation signal requires the inductor to be greater than
a minimum value, depending on output voltage, in order to

RESET Function
VOUT
The RSTB pin is pulled low when the output voltage falls
below 7% of the nominal regulation level, and floats when
the output is properly regulated. A pull-up resistor tied to the
output is needed to generate a logic high signal on this
open-drain pin. The pin can be left unconnected when not
used.
R
RSTB

When the output voltage drops out of regulation, the pin

goes low after a short noise-filtering delay (K ). It
RES_FILT
stays low for a delay time (adjustable) after the output goes
back to regulation, simplifying the connection to
a micro-controller.
The RSTB signal can either be used as a reset with delay
or a power good (no delay). The delay is determined by the
current into the RSTB pin, set by a resistor, as shown in
Figure 10.
Figure 10. Reset with Adjustable Delay
on a Single Pin
Use the following equation to determine the ideal reset
delay time using currents less than 500 mA:
The RSTB resistor is commonly tied to VOUT. A RSTB
resistor value that sets the current at the reset pin between
0.5 mA and 1 mA is not recommended due to the variation
of the threshold between a set delay time and power good.
Depending on the output voltage option, typical delay times
can be achieved with the following resistor values:

Enable
Synchronization
The NCV890430 is designed to accept either a logic-level
signal or battery voltage as an Enable signal. However, if
voltages above 40 V are expected, EN should be tied to VIN
through a 10 kW resistor in order to limit the current flowing
into the overvoltage protection of the pin.
A low signal on Enable induces a shutdown mode which
shuts off the regulator and minimizes its supply current to
less than 5 mA by disabling all functions.
Any number of NCV890430 can be synchronized to an
external clock. If a part does not have its switching
frequency controlled by the SYNC input, the part will be
driven at the 2 MHz default switching frequency. A rising
edge at the SYNC pin causes an NCV890430 to immediately
turn on the power switch. If another rising edge does not
arrive at the SYNC pin, the NCV890430 will start
controlling its own frequency within the Master Reassertion
Time. This allows uninterrupted operation if the clock is
turned off. An external pulldown resistor is not needed at the
SYNC pin if it is unconnected.
Once the switching regulator output is enabled, a soft-start
is always initiated.
Thermal Shutdown
A thermal shutdown circuit inhibits switching and resets
the soft-start circuit if internal temperature exceeds a safe
level indicated by the Thermal Shutdown Activation
Temperature. Switching is automatically restored when
temperature returns to a safe level based on the Thermal
Shutdown Hysteresis.
Exposed Pad
The exposed pad (EPAD) on the back of the package must
be electrically connected to both the analog and the power
electrical ground GND and PGND pins for proper,
noise-free operation. It is recommended to connect these 2
pins directly to the EPAD with a PCB trace. Refer to the
Recommended Layout for more information.
