NCP1562A, NCP1562B  
High Performance Active  
Clamp/Reset PWM Controller  
The NCP1562x is a family of voltage mode controllers designed  
for dcdc converters requiring highefficiency 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 softstop and  
a cycle skip current limit with a time threshold. Softstop circuitry  
powers down the converter in a controlled manner if a severe fault is  
detected. The cycle skip detector enables a softstop 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, cyclebycycle  
current limit with leading edge blanking (LEB), independent under  
and overvoltage detectors, adjustable output overlap delay,  
programmable maximum duty cycle, internal startup circuit and  
softstart.
