MCP1640EV-SBC产品概述
This evaluation board uses the MCP1640 in a high-efficiency (up to 96%), fixed frequency (500 MHz), step-up DC-DC converter. It demonstrates:
Easy-to-use and minimum number of external components power supply solution for applications powered by one-cell, two-cell, or three-cell alkaline, NiCd/NiMH; one-cell Li-Ion or Li-Polymer batteries
Selection of the best operating mode for efficiency (PWM/PFM)
A wide input voltage range (0.35 to 5.5 V) and low start-up voltage (0.65 V)
PCB layouts recommendation for SOT23-6 and 2 × 3 mm-8 DFN packages
Three common output voltages to evaluate: 2.0 V, 3.3 V and 5.0 V enable selection (when disabled, the MCP1640 disconnects the path from input to output for “true-disconnect”).
