Description
Pin Application Information
1
V
IN
Source Input Voltage
Input to start-up regulator. Input range 15V to 100V.
2
FB
Feedback Signal
Inverting input for the internal error amplifier. The non-inverting input is connected to
a 0.75V reference.
3
COMP
Output of the Internal
Error Amplifier
There is an internal 5 k
resistor pull-up on this pin. The error amplifier provides an
active sink.
4
REF
Precision 5 volt
reference output
Maximum output current: 10 mA. Locally decouple with a 0.1 F capacitor. Reference
stays low until the V
CC UV are satisfied.
5
HD
Main Buck PWM
control output
Buck switch PWM control output. The maximum duty cycle clamp for this output
corresponds to an off time of typically 240 ns per cycle. The LM5101 or LM5102 Buck
stage gate driver can be used to level shift and drive the Buck switch MOSFET.
6
LD
Buck Sync Switch
control output
Sync Switch control output. Inversion of HD output during normal operation. The
LM5101 or LM5102 lower drive can be used to drive the synchronous rectifier switch.
7
V
CC
Output of the internal
high voltage start-up
regulator. Regulated to
9 volts.
If an auxiliary winding raises the voltage on this pin above the regulation set-point, the
internal start-up regulator will shutdown, reducing the IC power dissipation.
8
PUSH
Output of the push-pull
drivers
Output of the push-pull gate driver. Output capability of 1.5A peak .
9
PULL
Output of the push-pull
drivers
Output of the push-pull gate driver. Output capability of 1.5A peak.
10
PGND
Power ground
Connect directly to analog ground.
11
AGND
Analog ground
Connect directly to power ground.
