... 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 ...
