NCP1562A Description
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.
