High Performance Active
Clamp/Reset PWM Controller
The NCP1562x is a family of voltage mode controllers designed
for dc-- dc converters requiring high-- efficiency and low parts count.
These controllers incorporate two in phase outputs with an overlap
delay to prevent simultaneous conduction and facilitates soft
switching. The main output is designed for driving a forward
converter primary MOSFET. The secondary output is designed for
driving an active clamp circuit MOSFET, a synchronous rectifier on
the secondary side, or an asymmetric half bridge circuit.

MARKING
DIAGRAMS
The NCP1562 family reduces component count and system size by
incorporating high accuracy on critical specifications such as
maximum duty cycle limit, undervoltage detector and overcurrent
threshold. Two distinctive features of the NCP1562 are soft-- stop and
a cycle skip current limit with a time threshold. Soft-- stop circuitry

powers down the converter in a controlled manner if a severe fault is
detected. The cycle skip detector enables a soft-- stop sequence if a
continuous overcurrent condition is present.
Additional features found in the NCP1562 include line feed--
forward, frequency synchronization up to 1.0 MHz, cycle-- by-- cycle
current limit with leading edge blanking (LEB), independent under
