F6456S Overview
Description
Note 1: The Pout (W) represents the thermal rating at Quasi-Resonant Operation, and the peak power output is obtained by approximately 120 to 140% of the above listed. When the output voltage is low and ONduty is narrow, the Pout (W) shall become lower than that of above.
Key Features
- Small temperature characteristics variation by adopting a comparator to compensate for temperature on the control part
- Low start-up circuit current (100uA max)
- Built-in Active Low-Pass Filter for stabilizing the operation in case of light load
- Avalanche energy guaranteed MOSFET with high VDSS
- The built-in power MOSFET simplifies the surge absorption circuit since the MOSFET guarantees the avalanche energy
- No VDSS de-rating is required
- Built-in constant voltage drive circuit
- Built-in soft drive circuit
- Built-in low frequency PRC mode (≒20kHz)
- Various kinds of protection functions
