Multi-topology PWM controller for isolated and non-isolated DC-DC
The MCP1632-BAE/MC: Switching at 600 kHz keeps the magnetics small, and the 85 % max duty cycle supports step-up ratios where the output is several times the input.
What the 600 kHz switching and synchronous rectification mean for the BOM
The 600 kHz fixed switching frequency lets the designer use a smaller inductor or transformer core than a 100 kHz part — the trade-off is higher core loss and driver dissipation, so the thermal budget in a 125 °C ambient needs a derating check. Synchronous rectification is built in — the controller drives an external N-channel FET on the secondary side, which replaces a Schottky diode and cuts the rectifier conduction loss by roughly the diode Vf / FET Rds(on) ratio.
Package and board-fit: 8-DFN with exposed pad
Supplied in tube format — not tape-and-reel, so pick-and-place lines need a tube feeder or a manual loading step for prototype runs.
RoHS3 compliant per the manufacturer's declaration, so it passes the EU material restriction check for new designs.
