NCP1562B, NCP1562A, High Performance Active Clamp/Reset PWM Controller
Pin Symbol Description 1 Vin Connect the input line voltage directly to this pin to enable the internal startup regulator.
A constant current source supplies current from this pin to the capacitor connected to the VAUX pin, eliminating the need for a startup resistor.
The charge current is typical
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 sy
NCP1562B 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
