SIGNAL NAME
FUNCTION DESCRIPTION
1
24
VCC
Logic Power
2
50%
Input selects maximum duty cycle (50% or 100%). Logic ''1'' selects 50% max duty cycle
and Output B is the complement of Output A. Logic ''0'' selects 100% and Output A is
in-phase with Output B.
3
SLEEP
This Input shuts down all functions on chip when asserted (Active Hi)
4
COMP
Output of the error amplifier. Place compensation network from this pin to VFB to stabilize
converter.
5
VFB
Negative Input to the error amplifier
6
ISENSE
Input Current sense pin used for current mode control
7
SOFT
This High impedance Input is used to limit the error amplifier output voltage. Applying an
RC circuit to this pin provides the standard softstart function. Pull the pin to ground to force
zero duty cycle. This input is internally shorted to ground when Enable (pin 17) is low or
Sleep (pin 3) is high or an Under Voltage is detected.
8
CSET
Works with Rset to establish oscillator free running frequency. Place cap from this Input pin
to ground. Can synchronize oscillator by overdriving this pin with an external frequency
source.
9
RSET
Works with Cset to establish oscillator free running frequency. Place resistor from this Input
pin to ground.
10
PWROK
Logical output of UV lockout circuit -- logic ''1'' indicates chip has valid Vcc
11
VREF
Buffered 3V Output reference voltage
12
VEE
Logic Ground
13
NIN
Auxiliary Op-Amp Inverting Input
14
PIN
Auxiliary Op-Amp Non-Inverting Input
15
AOUT
Auxiliary Op-Amp Output (Short circuit protected)
16
ENAUX
Input Enable of Auxiliary Op-Amp (Active Hi)
17
EN
Logic Input that enables the oscillator and output drivers. Reference voltage remains valid
(Active Hi).
18
19
DRVN
Output stage negative rail
20
OUT B
Totem pole Output B
21
OUTA
Totem pole Output A
22
23
DRVP
Output stage positive rail
