PIN FUNCTION DESCRIPTION
Pin No.
Symbol
Function
Description
1
Fmin
Timing Resistor
Connecting a resistor to this pin, sets the minimum oscillator frequency
reached for VFB is below 1.3 V.
2
Fmax
Frequency Clamp
A resistor sets the maximum frequency excursion.
3
DT
Deadtime
A simple resistor adjusts the deadtime length.
4
Css
SoftStart
Select the softstart duration.
5
FB
Feedback
Applying a voltage above 1.3 V on this pin increases the oscillation frequency
up to Fmax.
6
Ctimer
Timer Duration
Sets the timer duration in presence of a fault.
7
BO
BrownOut
Detects low input voltage conditions. When brought above Vlatch, it fully
latches off the controller.
8
Agnd
Analog Ground
9
Pgnd
Power Ground
10
A
Low Side Output
Drives the low side power MOSFET.
11
B
High Side Output
Drives the upper side power MOSFET.
12
Vcc
Supplies the Controller
13
Fast Fault
Quick Fault Detection
Fast shutdown pin, stops all pulses when brought high. Please look in the
description for more details about the fastfault sequence.
14
Slow Fault
Slow Fault Detection
When asserted, the timer starts to countdown and shuts down the controller at
the end of its time duration.
15
OUT
OPAMP Output
Internal transconductance amplifier.
16
NINV
OPAMP Noninverting
Noninverting pin of the OPAMP.
