Switched-mode power supply control circuit
NE/SE5562
DESCRIPTION
The NE/SE5562 is a single-output control circuit for switched-mode power supplies.
This single monolithic IC contains all control and protection features needed for full-featured switched-mode power supplies.
The 100mA source/sink output is designed to drive power FETs directly.
The associated output logic is designed to prevent double pulsing or cross-conduction current spiking on the output.
All of the control and protect features work cycle-by-cycle up to the maximum operating frequency of 600kHz.
For ease of interface, all digital inputs are TTL or
CMOS compatible.
