NCP1562A, NCP1562B

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

and overvoltage detectors, adjustable output overlap delay,

programmable maximum duty cycle, internal startup circuit and

soft−start.
