MIC2292/93

High-Frequency PWM White LED Drivers

with Internal Schottky Diode and OVP

General Description

Features

The MIC2292 and MIC2293 are high frequency, Pulse

Width Modulator (PWM) boost regulators optimized for

constant-current, white LED driver applications. Because

of their constant PWM switching frequencies of 1.6MHz

and 2MHz, respectively, the MIC2292/93 can use the

smallest external components, allowing designers to avoid

sensitive IF bands in their RF applications.

• 2.5V to 10V input voltage

• Output voltage up to 34V

• Internal Schottky diode

• 1.6MHz PWM operation (MIC2292)

• 2.0MHz PWM operation (MIC2293)

• Stable with ceramic capacitors

• 15V and 34V output overvoltage protection options

• 500mA switch current rating

• 95mV feedback voltage

The products feature an internal Schottky diode and two

levels of output overvoltage protection allowing a small

size and efficient DC/DC solution that requires only four

external components.

• <1% line and load regulation

• <1µA shutdown current

The 2.5V to 10V input voltage range of MIC2292/3 allows

direct operation from 1- and 2-cell Li Ion as well as 3- to 4-

cell NiCad/NiMH/Alkaline batteries. The MIC2292/3

products are available in a small size 2mm × 2mm 8-pin

MLF^®package and have a junction temperature range of

• Over-temperature protection

• UVLO

• 8-pin (2mm × 2mm) MLF^®package

• –40°C to +125°C junction temperature range

–40°C to +125°C.
