MIC2289 Datasheet 2mm 2mm White Led Driver With Internal Schottky Diode And Ovp

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: MIC2289 Micrel MIC2289 2mm × 2mm White LED Driver with Internal Schottky Diode and OVP.

General Description

The MIC2289 is a PWM (pulse width modulated), boostswitching regulator that is optimized for constant-current white LED driver applications.

The MIC2289

Key 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. To optimize efficiency, the feedback voltage is set to only 95mV. This reduces power dissipation in the current set resistor and allows the lowest total output voltage, hence minimal current draw from the battery. The MIC2289 implements a constant frequency 1.2MHz PWM control scheme. The high frequency, PWM operation saves b.
