Microchip Technology, Inc. DC DC Switching Controllers MCP1631HV-500E/ST

The MCP1631HV-500E/ST is a high-speed pulse width modulator (PWM) designed for programmable switching battery charger applications. It operates with a high input voltage range of +3.5V to +16V and provides a regulated output voltage of +5.0V with a maximum current of 250 mA. This device features peak current mode control, an integrated high current low side MOSFET driver capable of 1A peak, and a shutdown mode that reduces quiescent current to 2.4 µA. The MCP1631HV-500E/ST is suitable for charging multiple battery chemistries, including Li-Ion, NiMH, NiCd, and Pb-Acid, making it versatile for various applications. It includes integrated protection features such as overvoltage comparator, undervoltage lockout, and overtemperature protection. The device can be combined with a microcontroller for enhanced control over output voltage, current, switching frequency, and maximum duty cycle, allowing for intelligent power system development. Available in a 20-lead TSSOP package, this product is ideal for engineers looking for a robust solution for high input voltage applications in battery management and LED lighting systems.
