Synchronous PWM Controller
The NCP3030 is a PWM device designed to operate from a wide
input range and is capable of producing an output voltage as low as
0.6 V. The NCP3030 provides integrated gate drivers and an internally
set 1.2 MHz (NCP3030A) or 2.4 MHz (NCP3030B) oscillator. The
NCP3030 also has an externally compensated transconductance error
amplifier with an internally fixed soft−start. Protection features
include lossless current limit and short circuit protection, output
overvoltage protection, output undervoltage protection, and input
undervoltage lockout. The NCP3030 is currently available in a
SOIC−8 package.

PIN FUNCTION DESCRIPTION
Pin Pin Name Description
1 V
CC
The V
CC
pin is the main voltage supply input. It is also used in conjunction with the VSW pin to sense current
in the high side MOSFET.
2 COMP The COMP pin connects to the output of the Operational Transconductance Amplifier (OTA) and the positive
terminal of the PWM comparator. This pin is used in conjunction with the FB pin to compensate the voltage
mode control feedback loop.
3 FB The FB pin is connected to the inverting input of the OTA. This pin is used in conjunction with the COMP pin to
compensate the voltage mode control feedback loop.
4 GND Ground Pin
5 LSDR The LSDR pin is connected to the output of the low side driver which connects to the gate of the low side
N−FET. It is also used to set the threshold of the current limit circuit (I
SET
) by connecting a resistor from LSDR
to GND.
6 VSW The VSW pin is the return path for the high side driver. It is also used in conjunction with the V
CC
pin to sense
current in the high side MOSFET.
7 HSDR The HSDR pin is connected to the output of the high side driver which connects to the gate of the high side
N−FET.
8 BST The BST pin is the supply rail for the gate drivers. A capacitor must be connected between this pin and the
VSW pin.
