Microchip Technology, Inc. Voltage Regulators - DC DC Switching Regulators MIC2145YMM-TR

The MIC2145YMM-TR is a boost switching regulator designed to deliver over 2.5W of output power with an input voltage range of 2.4V to 16V. It is 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, making it versatile for various applications. This regulator operates at a typical frequency of 450kHz, allowing the use of small surface mount components, which is beneficial for space-constrained designs. It features a low quiescent current of 200¬µA and a shutdown current of only 0.5¬µA, contributing to its efficiency. The internal switch has a low on-resistance, enabling high efficiency and performance. The MIC2145YMM-TR includes programmable peak current limit capabilities, allowing users to optimize for efficiency and inductor size. It is available in both MSOP-8 and 3mmvó3mm MLF,Ñ¢-10L packages, with an operating temperature range from -40¬8C to +85¬8C. Typical applications include flash LED drivers, LCD bias supplies, and local voltage conversion.
