PACKAGE PIN DESCRIPTION
PACKAGE PIN #
SOIC−16
PIN SYMBOL FUNCTION
1, 2, 3, 4, 6 V
ID0
−V
ID4
Voltage ID DAC input pins. These pins are internally pulled up to 5.0 V if left open. V
ID4
selects
the DAC range. When V
ID4
is high (logic one), the Error Amp reference range is 2.14 V to 3.45 V
with 100 mV increments. When V
ID4
is low (logic zero), the Error Amp 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 C
OFF
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) on this pin
disables operation and places the CS5165A into a low current sleep mode.
9 V
CC
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 Power Good Output. Open collector output drives low when V
FB
is out of regulation. Active 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.
16 V
FB
Error Amp, PWM Comparator, and Low V
FB
Comparator feedback input.
