PIN SYMBOL

FUNCTION

SO−16L

1, 2, 3, 4, 6

reference voltage 1.34 V to 2.09 V with 50 mV increments.

5

SS

Soft Start Pin. A capacitor from this pin to LGND sets the Soft Start and fault timing.

7

Off−Time Capacitor Pin. A capacitor from this pin to LGND sets both the normal and

extended off time.

8

ENABLE

Output Enable Input. This pin is internally pulled up to 1.8 V. A logic Low (< 0.8 V) on this

pin disables operation and places the CS5165H into a low current sleep mode.

9

Input Power Supply Pin.

10

GATE(H)

High Side Switch FET driver pin.

11

PGND

High current ground for the GATE(H) and GATE(L) pins.

12

GATE(L)

Low Side Synchronous FET driver pin.

13

PWRGD

tive when ENABLE input is low.

14

LGND

Reference ground. All control circuits are referenced to this pin.

15

COMP

Error Amp output. PWM Comparator reference input. A capacitor to LGND provides Error

Amp compensation.
