DESCRIPTION

NAME

NO.

BOOT1 provides a bootstrapped supply for the high side FET driver for PWM1, enabling the gate of the high

BOOT1

27

I

side FET to be driven above the input supply rail. Connect a capacitor from BOOT1 to SW1 pin and a Schottky

diode from this pin to VREG.

BOOT2 provides a bootstrapped supply for the high side FET driver for PWM2, enabling the gate of the high

BOOT2

18

I

side FET to be driven above the input supply rail. Connect a capacitor from BOOT2 to SW2 pin and a Schottky

diode from this pin to VREG.

Filtered input from the VREG pin. A 10-

Ω resistor should be connected between VREG and BP5 and a 1.0-μF

BP5

8

I

ceramic capacitor should be connected from BP5 to ground.

Digital clock signal for synchronizing slave controllers to the master CLKIO frequency and is either 6 or 8 times

CLKIO

28

O

the PWM switching frequency.

COMP1

35

O

Output of the error amplifier, CH1. The voltage at this pin determines the duty cycle for the PWM1.

(1)

It is often necessary to refer to a pin or pins that are used in CH1 and/or CH2. The shortcut nomenclature used is the pin name with a

lower case 'x' to mean either or both channels. For example, TRKx refers to TRK1 and/or TRK2.
