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 V
FB
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.
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.
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
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
OUTB
Totem pole Output B
21
OUTA
Totem pole Output A
22
23
DRVP
Output stage positive rail
