Package Pin Description
FUNCTION
Voltage ID DAC inputs. These pins are internally pulled up to 5V if left open.
VID4 selects the DAC range. When VID4 is high (logic one), the Error Amp ref-
erence range is 2.14V to 3.54V with 100mV increments. When VID4 is low (logic
zero), the Error amp reference voltage is 1.34V to 2.09V with 50mV increments.
Soft Start Pin. A capacitor from this pin to LGnd sets the Soft Start and fault
timing.
Off-Time Capacitor Pin. A capacitor from this pin to LGnd sets both the nor-
mal and extended off time.
Output Enable Input. This pin is internally pulled up to 1.8V. A logic Low
( < 0.8V) on this pin disables operation and places the CS5165H into a low
current sleep mode.
Input Power Supply Pin.
High Side Switch FET driver pin.
High Current ground for the GATE(H) and GATE(L) pins.
Low Side Synchronous FET driver pin.
Power Good Output. Open collector output drives low when VFB is out of
regulation. Active when ENABLE input is low
Reference ground. All control circuits are referenced to this pin.
Error Amp output. PWM Comparator reference input. A capacitor to LGnd
provides Error Amp compensation.
Error Amp, PWM Comparator, and Low VFB Comparator feedback input.
