MCP1651ST-E/MS Description

Short technical summary and product information.

The MCP1651ST-E/MS from Microchip Technology is a 750 kHz gated oscillator boost controller designed for high-power, portable applications. It can deliver over 5 watts of output power and supports output voltages from 3.3V to over 100V.

 

This controller operates over an input voltage range of 2.7V to 5.5V, making it suitable for battery-powered devices. It features a low operating quiescent current of 120 µA and a shutdown current of less than 0.1 µA. The device supports SEPIC and Flyback topologies and includes features such as current limit, enable, low battery detection, and power good indication.

 

The MCP1651ST-E/MS is packaged in an 8-MSOP (0.118", 3.00mm Width) surface mount package. Its high switching frequency helps minimize the size of external components, saving board space and cost. The operating temperature range is -40°C to +125°C (TJ).

 

Key electrical specifications include a maximum duty cycle of 80% and a voltage feedback tolerance of 0.6%. The controller is a single-output, single-phase device with a transistor driver output type.
