FUNCTION
16 Lead SO Narrow
1
GATE
External power switch driver with 1.0 A peak capability.
2
ISENSE
Current sense amplifier input.
3
SYNC (CS51021A/3A)
Bi−directional synchronization. Locks to the highest frequency.
3
SLEEP (CS51022A/4A)
Active high chip disable. In sleep mode, VREF and GATE are turned off.
4
SLOPE
Additional slope to the current sense signal. Internal current source charges the external capacitor.
5
UV
Undervoltage protection monitor.
6
OV
Overvoltage protection monitor.
7
RTCT
Timing resistor RT and capacitor CT determine oscillator frequency and maximum duty cycle, DMAX.
8
ISET
Voltage at this pin sets pulse−by−pulse overcurrent threshold, and second threshold (1.33 times
higher) with Soft Start retrigger (hiccup mode).
9
VFB
Feedback voltage input. Connected to the error amplifier inverting input.
10
COMP
Error amplifier output. Frequency compensation network is usually connected between COMP and
VFB pins.
11
SS
Charging external capacitor restricts error amplifier output voltage during the start or fault
conditions (hiccup).
12
LGND
Logic ground.
13
VREF
5.0 V reference voltage output.
14
VCC
Logic supply voltage.
15
PGND
Output power stage ground connection.
16
VC
Output power stage supply voltage.
