MIC2292/93C www.DataSheet4U.com High Frequency PWM White LED Drivers with Internal Schottky Diode and OVP General Description The MIC2292C and MIC2293C 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 MIC2292/93C 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.
