Регуляторы напряжения - Импульсные регуляторы MIC2290YML TR

Импульсный повышающий DC-DC стабилизатор , регулируемый, 2.5В-10В (Vin), 3В-34В, 500мА, MLF-8

The MIC2290YML TR is a PWM Boost Regulator feature an internal Schottky diode that reduces circuit board area. High power density is achieved with the MIC2290's internal 34V/0.5A switch, allowing it to power large loads. The MIC2290 implements a constant frequency 1.2MHz PWM control scheme. The high frequency operation saves board space by reducing external component sizes. The fixed frequency PWM topology also reduces switching noise and ripple to the input power source. The MIC2290's wide 2.5 to 10V input voltage allows direct operation from 3- to 4-cell NiCad/NiMH/Alkaline batteries, 1- and 2-cell Li-ion batteries, as well as fixed 3.3V and 5V systems.
