Switching frequency is programmable from 31.25 kHz to 2 MHz via the I²C serial interface, which also handles output voltage trim and fault monitoring — no external resistor divider for frequency setpoint, so the BOM count stays low for a compact 28-QFN 5x5 mm layout. ## Active production — ROHS3, no synchronous rectifier The controller does not include an internal synchronous rectifier driver — the output stage drives an external transistor, so the designer selects the rectification scheme (diode or sync FET) at the system level.","metaTitle":"MCP19114-E/MQ Microchip Multi-Topology Controller, 42V","metaDescription":"Microchip MCP19114-E/MQ multi-topology PWM controller, 4.5-42V supply, I²C interface, AEC-Q100 automotive qualified.
