MCP1631T-E/ML Description

Short technical summary and product information.

The MCP1631T-E/ML from Microchip Technology is a high-speed analog pulse width modulator (PWM) controller used in the development of intelligent power systems. When combined with a microcontroller, it can control the power system duty cycle for output voltage or current regulation. This device supports Sepic topology and operates with input voltages ranging from 3.5V to 16V.

 

Key electrical specifications include regulated output voltage options of +3.3V or +5.0V, with a maximum output current of 250 mA. It features peak current mode control and an integrated high-current low-side MOSFET driver. The controller operates at a high switching frequency of 2 MHz and includes features like undervoltage lockout (UVLO) and internal overtemperature protection. Shutdown mode reduces quiescent current to a typical 2.4 µA.

 

The MCP1631T-E/ML is housed in a 20-VFQFN exposed pad package, designed for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). This controller is suitable for applications such as high input voltage programmable switching battery chargers supporting multiple chemistries, LED lighting, and constant current SEPIC power train designs.
