The MCP1653S-E/UN from Microchip Technology is a versatile DC DC switching controller designed for high-power boost applications. It operates with an input voltage range of 2.0V to 5.5V and features a fixed 750 kHz gated oscillator switching frequency. This controller is capable of SEPIC and Flyback topologies and supports output power capability over 5 Watts, with output voltages ranging from 3.3V to over 100V.
Key electrical features include adaptable duty cycle for battery or wide-input voltage applications, low operating quiescent current of 120 µA, and shutdown control with quiescent current below 0.1 µA. It also includes features like peak current limit, adjustable output voltage/current, low battery detection, and power-good indication. The device offers two undervoltage lockout (UVLO) options: 2.0V or 2.55V.
Packaged in a 10-pin MSOP, the MCP1653S-E/UN is suitable for space-limited designs. It is designed for surface mount applications and operates within a temperature range of -40°C to +125°C. The controller is ideal for applications such as high-voltage bias supplies, white LED drivers, and local power supplies.
