MIC2288YML TR

MICREL SEMICONDUCTOR  MIC2288YML TR  直流-直流开关升压稳压器, 可调, 2.5V-10V输入, 3.6V-34V输出, 1A输出, MLF-8

The is a PWM DC-to-DC boost Switching Regulator for use with TFT-LCD bias supply. High power density is achieved with the MIC2288"s internal 34V/1A switch, allowing it to power large loads in a tiny footprint. The MIC2288 implements a constant frequency, 1.2MHz PWM, current-mode control scheme with internal compensation that offers excellent transient response and output regulation performance. The high frequency operation saves board space by allowing small, low-profile, external components. The fixed frequency PWM topology also reduces spurious switching noise and ripple to the input power source.
