Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. 60 second maximum above 183 C.

High Side Switch FET driver pin for channel 1.
Low Side Synchronous FET driver pin for channel 1.
Ground pin for all circuitry contained in the IC. This pin is internally bonded to the substrate of the IC.
Power input for GATE(H)1 and GATE(H)2 pins.
Positive input for channel 1 overcurrent comparator.
Negative input for channels 1 and 2 overcurrent comparator.
Error amplifier inverting input for channel 1.
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.
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.
Error amplifier inverting input for channel 2.
Error amplifier noninverting input for channel 2.
Positive input for channel 2 overcurrent comparator.
Oscillator frequency pin. A resistor from this pin to ground sets the oscillator frequency.
Input Power supply pin.
Low Side Synchronous FET driver pin for channel 2.
High Side Switch FET driver pin for channel 2.
Negative Current Sense for Channels 1 and 2
Compensation Capacitor for Channel 1 or 2
Voltage Feedback Input for Channel 1 or 2
Positive Current Sense for Channel 1 or 2
