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.
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.
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-
