Microchip Technology, Inc. DC DC Switching Controllers MCP1631VHV-330E/SS

The MCP1631VHV-330E/SS is a high-speed analog pulse width modulator (PWM) designed for intelligent power system applications. It operates with a high input voltage range of +3.5V to +16V and provides a regulated output voltage of 3.3V with a maximum current of 250 mA. This device features voltage mode control, making it suitable for programmable switching battery charger designs that support multiple battery chemistries, including Li-Ion, NiMH, NiCd, and Pb-Acid. The MCP1631VHV integrates several key functionalities, including an error amplifier, battery current and voltage sensing amplifiers, and an overvoltage comparator. It also includes a low-side MOSFET driver capable of handling peak currents up to 1A. The device supports external oscillator input for setting switching frequency and maximum duty cycle, enhancing design flexibility. Additionally, it features a shutdown mode that reduces quiescent current to 2.4 µA, along with internal overtemperature protection and undervoltage lockout (UVLO) capabilities. This product is available in a 20-lead SSOP package, making it suitable for compact designs. Its combination of features and flexibility makes the MCP1631VHV-330E/SS a viable option for engineers looking to implement efficient power management solutions in their projects.
