The MCP1653R-E/UN from Microchip Technology is a versatile 750 kHz gated oscillator boost controller. It is designed for high-power, portable applications, capable of delivering over 5 watts of output power. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered applications.
This controller supports multiple topologies, including Boost, Flyback, and SEPIC, offering flexibility in design. It features adaptable duty cycles for battery or wide-input voltage applications, with a maximum duty cycle of 80%. Key control features include current limit, enable, low battery detection, and power good indication.
The MCP1653R-E/UN is packaged in a compact 10-MSOP (Surface Mount) package, ideal for space-constrained designs. It operates within a temperature range of -40°C to 125°C (TJ). The low operating quiescent current of 120 µA at no load and shutdown current below 0.1 µA contribute to power efficiency in portable devices.
Applications for this controller include high-power boost applications, high-voltage bias supplies, white LED drivers, and LCD bias supplies. Its design facilitates smaller external inductor and capacitor components, saving board space and cost.
