MCP1631HVT-500E/SS is a DC to DC switching controller produced by Microchip Technology. It is designed for use in automotive and industrial applications. The device features 1A of continuous output current, and it operates from a single 7.2V to 30V input voltage range. The controller provides 3.3V, 5.0V, 12V, and 15V outputs with efficiency up to 94%. It is also capable of driving up to five external power MOSFETS with up to 1A of output current.

The MCP1631HVT-500E/SS operates by controlling the switching of external MOSFETs to produce a desired low voltage output in applications that require compliance with standards such as CANbus and LINbus systems. The controller is capable of operating in various topologies, including boost, flyback, single-ended primary inductance converter, and isolated forward mode. In addition, the device features an embedded current sense comparator that can be used to monitor the output current and protect from short circuit or overload events.

The operating supply voltage of the MCP1631HVT-500E/SS is programmable through a jumper across PGC1, PGC2 and VREF pins. The device has two sets of overvoltage protection (OVP) and two sets of programmable under-voltage protection (UVLO). The device also has a precision 2.5% internal reference that provides a reliable and cost-effective solution for generating precise operating supply voltages.

The MCP1631HVT-500E/SS consists of an integrated 32-bit ARM cortex-M3 processor, on-chip memory and data blocks. It has an integrated linear power supply that ensures direct connection of the device to the system’s 12V supply rail with no external components needed. The device also includes an on-chip multiplexer, LVDS-compatible inputs, a precision reset circuit, watchdog timer, and general-purpose I/O pins.

The MCP1631HVT-500E/SS is designed for applications that require precise control over output voltage, current and temperature. It is designed for applications such as DC to DC converters, battery cell packs, LiDAR systems, motor controls, and industrial IoT applications. It can be used in automotive, industrial and communications applications where advanced power control is required.
