FUNCTION
Oscillator-Timing Resistor. Connect a resistor from RT to AGND to set the internal oscillator
frequency.
External-Clock Sync Input. Connect SYNC to AGND when not using an external clock.
Hysteresis Input
Slope-Compensation Capacitor Connection
Dead-Time Resistor Connection. Connect a resistor from DT to AGND to program the
output dead time. Connect to REG5 for NDRVA and NDRVB maximum 50% duty cycle.
Externally Programmable Undervoltage Lockout. UVLO/EN programs the input start
voltage. Connect UVLO/EN to AGND to disable the output.
Error-Amplifier Inverting Input
Error-Amplifier Output
Fault-Integration Input. A capacitor connected to FLTINT charges with an internal 60μA

FLTINT
current source during persistent current-limit faults. Switching terminates when V FLTINT is
2.8V. An external resistor connected in parallel discharges the capacitor. Switching
resumes when V FLTINT drops to 1.6V.

Analog Ground. Connect to PGND.
Power Ground. Connect to AGND through a ground plane.
Gate-Driver Output B. Connect NDRVB to the gate of the external N-channel FET.
Gate-Driver Output A. Connect NDRVA to the gate of the external N-channel FET.
9V Linear-Regulator Output. Decouple V CC with a minimum 1μF ceramic capacitor to
AGND; also internally connected to the FET drivers.
Power-Supply Input. IN provides power for all internal circuitry except the gate driver.
Decouple IN with 0.1μF to AGND (see the Typical Operating Circuit ).
5V Linear-Regulator Output. Decouple REG5 to AGND with 0.1μF ceramic capacitor.
Exposed Paddle. Connect to GND.
