MIC2571-2YMM-TR

Voltage Regulators - DC DC Switching Regulators Overview

The MIC2571-2YMM-TR is a micropower boost switching regulator manufactured by Microchip Technology, designed to operate from a single alkaline, nickel-metal-hydride, or lithium cell. It accepts a positive input voltage between 0.9V and 15V with a typical no-load supply current of 120µA. This adjustable output version allows configuration for voltages ranging from the input level up to 36V using an external resistor network. The device features a fixed switching frequency of 20kHz and supports synchronization via an external SYNC connection. It requires only four external components and is housed in an 8-lead MSOP package with an operating temperature range of –40°C to +85°C.
