Description
Pin Application Information
12
CS
Current sense input
Current sense input to the PWM comparator (current mode control). There is a 50 ns
leading edge blanking on this pin. If CS exceeds 0.5V, the PWM controller will go into
cycle by cycle current limit.
13
SS
Soft-Start control
An external capacitor and an internal 10 A current source, set the soft-start ramp.
Both HD and LD will be forced to a low state if the SS pin is below the shutdown
threshold of 0.45V.
14
TIME
Push-Pull overlap and
dead time control
An external resistor (R
SET) sets the overlap time or dead time for the push-pull outputs.
A resistor connected between TIME and GND produces overlap. A resistor connected
between TIME and REF produces dead time.
15
RT / SYNC
Oscillator timing
resistor pin and sync
An external resistor sets the oscillator frequency. This pin will also accept an external
oscillator.
16
UVLO
Line Under-Voltage
Shutdown
An external divider from the power source sets the shutdown levels. Threshold of
operation equals 2.5V. Hysteresis is set by a switched internal current source (20 A).
LLP DAP
SUB
Die substrate
The exposed die attach pad of the LLP package should be connected to a PCB
thermal pad at ground potential. For additional information on using National
Semiconductor's No Pull Back LLP package, please refer to Application Note
AN-1187: Leadless Leadframe Package (LLP).
