The MCP1651R-E/MS from Microchip Technology is a versatile 750 kHz gated oscillator boost controller designed for high-power, portable applications. It is capable of delivering over 5 watts of output power and supports output voltages from 3.3V up to over 100V. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered systems.
Key features include an adaptable duty cycle for battery or wide-input voltage applications, a low operating quiescent current of 120 µA, and shutdown control with current consumption below 0.1 µA. The controller supports SEPIC and Flyback topologies and integrates features like peak current limit, enable, low battery detection, and power-good indication. Its high switching frequency minimizes the size of external components, saving board space and cost.
The MCP1651R-E/MS is packaged in a compact 8-MSOP (8-TSSOP, 8-MSOP) surface-mount package. The operating temperature range is -40°C to +125°C (TJ). This controller is ideal for applications requiring high-power boost, high-voltage bias supplies, white LED drivers, and various local voltage regulation needs.
This device is suitable for applications such as local 3.3V to 5.0V supplies, 3.3V to 12V supplies, and 5.0V to 12V supplies, as well as LCD bias supplies.
