Product Description

Microchip MCP16312-E/MS is a synchronous step-down DC-DC buck converter designed for efficient power regulation in electronic circuits. It integrates a high-side and low-side N-channel MOSFET switches, operates with fixed frequency peak current mode control at 500 kHz, and supports an input voltage range from 4.4V up to 30V. The device provides an adjustable output voltage spanning 2.0V to 24V with a maximum continuous output current of 1A, achieving efficiency of up to 95%.

The MSOP package and surface-mount mounting type offer a compact footprint with 3mm x 3mm x 1.1mm dimensions and 8 pins, suitable for densely packed PCB layouts in industrial, automotive, and consumer electronics.

Internal features include soft-start (300 μs), internal compensation circuitry, peak current limiting, under-voltage lockout, and over-temperature protection to ensure robust and reliable operation. Low device shutdown and quiescent currents help reduce battery drain in portable or low-power systems.

The buck converter complies with EIA/JESD51-3, RoHS standards, and ISO 9001 manufacturing quality. It is qualified to AEC-Q100 Rev. G Grade 1 standards, supporting demanding automotive industry requirements for temperature and reliability.

Operates efficiently over a broad 4.4V to 30V input voltage range. Adjustable output voltage from 2.0V to 24V with 1A output capability. Fixed 500 kHz PWM switching frequency for minimized external components. Compact MSOP surface mount package measuring 3x3x1.1 mm with 8 pins.

Low shutdown and quiescent current reduce power consumption. Internal over-temperature shutdown and under-voltage lockout protections. Automotive-grade qualification with wide operating temperature range (-40°C to 125°C).

Compliant with RoHS and ISO 9001 quality standards.

This product is ideal for power supply circuits in industrial electronics, automotive systems, consumer devices, and any application requiring precise and efficient DC-DC voltage step-down conversion. Microchip's MCP16312-E/MS enhances power efficiency, size reduction, and system reliability.
