MIC2292-15BML-TR

MIC2292/93 High-Frequency PWM White LED Drivers with Internal Schottky Diode and OVP Features General Description • • • • • • • • • • • • • • • • 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 1.6 MHz and 2 MHz, 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 Range Output Voltage up to 34V Internal Schottky Diode 1.6 MHz PWM Operation (MIC2292) 2.0 MHz PWM Operation (MIC2293) Stable with Ceramic Capacitors 15V, and 34V Output OVP Options 1.2 MHz PWM Operation 500 mA Switch Current Rating 95 mV Feedback Voltage
