The MCP1631-E/ML from Microchip Technology is a high-speed analog pulse width modulator (PWM) designed for intelligent power systems. It operates within a voltage range of 3V to 5.5V and maintains functionality across an extended temperature range of -40°C to 125°C.
This controller supports programmable switching battery charger designs and can be combined with a microcontroller for enhanced control. It features peak current mode control and operates at a high switching frequency of 2 MHz. The device is available in a 20-QFN (4x4) package, suitable for surface mount applications.
Key features include integrated error amplifiers, battery current and voltage sense amplifiers, and an overvoltage comparator. It also has an integrated high current low-side MOSFET driver and a shutdown mode that reduces quiescent current to a typical 2.4 µA. Internal overtemperature protection and undervoltage lockout (UVLO) are also included for robustness.
Applications for the MCP1631-E/ML include high input voltage programmable switching battery chargers supporting multiple chemistries like Li-Ion, NiMH, NiCd, and Pb-Acid. It is also suitable for LED lighting applications and constant current SEPIC power train designs.
