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
current source during persistent current-limit faults. Switching terminates when V
2.8V. An external resistor connected in parallel discharges the capacitor. Switching
resumes when V
Current-Sense Resistor Connection
Analog Ground. Connect to PGND.
Power Ground. Connect to AGND through a ground plane.
G ate- D r i ver O utp ut B. C onnect N D RV B to the g ate of the exter nal N - channel FE T.
Gate-Driver Output A. Connect NDRVA to the gate of the external N-channel FET.
9V Linear-Regulator Output. Decouple V
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.
