MIC2292 Datasheet | Micrel Semiconductor

.. MIC2292/93 Micrel MIC2292/93 High Frequency PWM White LED Drivers with Internal Schottky Diode and OVP General Description The MIC2292 and MIC2293 are high frequency, Pulse Width Modulator (PWM) boost regulators optimized for constantcurrent, 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 ponents, 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...
