The MCP1653ST-E/UN from Microchip Technology is a versatile boost controller designed for high-power, portable applications. It operates at a 750 kHz switching frequency, enabling the use of smaller external components and saving board space.
This controller supports an input voltage range of 2.0V to 5.5V, making it suitable for battery-powered devices and regulated input voltages. It is capable of delivering over 5 watts of output power and can achieve output voltages from 3.3V up to over 100V. The device features adaptable duty cycles, with a maximum of 80% when input voltage is below 3.8V and 56% when above 3.8V, optimizing performance across different input conditions.
Key features include a low operating quiescent current of 120 µA at no load and shutdown current below 0.1 µA. It also incorporates control features such as current limit, enable, low battery detection, and power good indication. The MCP1653ST-E/UN is packaged in a 10-MSOP or 10-TFSOP (0.118", 3.00mm Width) and is designed for surface mount applications.
This boost controller is ideal for applications requiring high-voltage bias supplies, white LED drivers, flashlights, and local power supplies ranging from 3.3V to 12V.
