Microchip Technology, Inc. Voltage Regulators - DC DC Switching Regulators MIC2145BMM-TR

The MIC2145BMM-TR is a compact boost switching regulator capable of delivering over 2.5W of output power. It operates within an input voltage range of 2.4V to 16V, making it suitable for applications involving one-cell Li-Ion and 3- to 4-cell alkaline/NiCad/NiMH batteries. The output voltage is adjustable up to 16V, allowing flexibility in design. This regulator features a typical switching frequency of 450kHz, which enables the use of small surface mount components, thus saving board space. It has a low quiescent current of 200¬µA and a shutdown current of only 0.5¬µA, contributing to its efficiency in portable applications. The MIC2145BMM-TR includes a programmable peak current limit, allowing users to optimize performance based on specific application requirements. The device is available in both MSOP-8 and 3mmvó3mm MLF,Ñ¢-10L packages and operates over an ambient temperature range of -40¬8C to +85¬8C. It is suitable for various applications, including flash LED drivers, LCD bias supplies, and local voltage conversion.
