Micrel MIC2289-24YML

DC DC 稳压器2.5V10V750mA（开关）

Overview

The MIC2289 is a PWM (pulse width modulated), boost switching regulator that is optimized for constant-current white LED driver applications. The MIC2289 features an internal Schottky diode and three levels of output overvoltage protection providing a small size and efficient DC/DC solution that requires only four external components.

• 2.5V to 10V input voltage• Output voltage up to 34V• Internal Schottky diode• 15V, 24V, 34V output OVP options• 1.2 MHz PWM operation• Over 500mA switch current• 95mV feedback voltage• <1% line and load regulation• <1µA shutdown current• Overtemperature protection• UVLO• 2mm × 2mm 8-pin MLF® package• –40°C to +125°C junction temperature range
