Регуляторы напряжения - Импульсные регуляторы MIC2253-06YML TR

Импульсный повышающий DC-DC стабилизатор , регулируемый, 2.5В-10В (Vin), 3В-30В, 3.5А, MLF-12

The MIC2253-06YML TR is a high-efficiency PWM DC-to-DC Boost Regulator with OVP and soft-start function. The 3.5A minimum switch current limit combined with a 1MHz switching frequency allows the MIC2253 to use smaller inductors and deliver high power in a tiny solution size. The 2.5 to 10V input voltage range of MIC2253 allows direct operation from 1 and 2 cell Li-ion as well as 3 to 4 cell NiCad, NiMH, Alkaline or lithium batteries. Maximum battery life is assured with a low 0.1µA shutdown current. To prevent a high inrush current, a minimum 1ms soft-start period is set by default and the MIC2253 has the ability to extend the soft-start period with an external capacitor.
