Microchip MCP16311-E/MS MCP16311-E/MS DC-DC Switching Buck Step Down Regulator Adjustable 4.4V-30Vin 2V-24Vout 1Aout MSOP-8

The MCP16311-E/MS is a compact, high-efficiency, fixed frequency, synchronous step-down DC-DC Converter. Integrated features include a high-side and a low-side switch, fixed frequency peak current mode control, internal compensation, peak current limit and over-temperature protection. This provides all the active functions for local DC-DC conversion, with fast transient response and accurate regulation. High converter efficiency is achieved by integrating the current-limited, low-resistance, high-speed high-side and low-side switches and associated drive circuitry. It is capable of running in PWM/PFM mode. It switches in PFM mode for light load conditions and for large buck conversion ratios. This results in a higher efficiency over all load ranges. This can supply up to 1A of continuous current while regulating the output voltage from 2 to 12V.

• Up to 95% efficiency
• Integrated N-channel low and high-side switches
• 0.8V Stable reference voltage
• Automatic pulse frequency modulation/pulse-width modulation
• 3µA Typical low device shutdown current
• 44µA (non-switching, PFM mode) Low device quiescent current
• Internal compensation
• 300µs (EN low to high) Internal soft-start
• Peak current mode control
• Cycle-by-cycle peak current limit
• Over-temperature protection
