PACKAGE PIN DESCRIPTION
PIN NO.
PIN SYMBOL
FUNCTION
1
GATE(H)1
High Side Switch FET driver pin for channel 1.
2
GATE(L)1
Low Side Synchronous FET driver pin for channel 1.
3
GND
Ground pin for all circuitry contained in the IC. This pin is internally bonded to the substrate of the IC.
4
BST
Power input for GATE(H)1 and GATE(H)2 pins.
5
IS+1
Positive input for channel 1 overcurrent comparator.
6
IS1
Negative input for channel 1 overcurrent comparator.
7
V
FB1
Error amplifier inverting input for channel 1.
8
COMP1
Channel 1 Error Amp output. PWM Comparator reference input. A capacitor to LGND provides Error
Amp compensation. The same capacitor provides Soft Start timing for channel 1. This pin also
disables the channel 1 output when pulled below 0.3 V.
9
COMP2
Channel 2 Error Amp output. PWM Comparator reference input. A capacitor to LGND provides Error
Amp compensation and Soft Start timing for channel 2. Channel 2 output is disabled when this pin is
pulled below 0.3 V.
10
V
FB2
Error amplifier inverting input for channel 2.
11
IS2
Negative input for channel 2 overcurrent comparator.
12
IS+2
Positive input for channel 2 overcurrent comparator.
13
R
OSC
Oscillator frequency pin. A resistor from this pin to ground sets the oscillator frequency.
14
V
CC
Input Power supply pin.
15
GATE(L)2
Low Side Synchronous FET driver pin for channel 2.
16
GATE(H)2
High Side Switch FET driver pin for channel 2.
