MIC2606

MIC2605/6 0.5A, 1.2MHz / 2MHz Wide Input Range Boost Regulator with Integrated Switch and Schottky Diode General Description Features The MIC2605/6 is a 1.2MHz/2MHz, PWM DC/DC boost switching regulator available in a 2mm x 2mm MLF® package. High power density is achieved with the MIC2605/6’s internal 40V/0.5A switch and schottky diode, allowing it to power large loads in a tiny footprint. The MIC2605/6 implements constant frequency 1.2MHz/2MHz PWM current mode control. The MIC2605/6 offers internal compensation that offers excellent transient response and output regulation performance. The high frequency operation saves board space by allowing small, low-profile external components. The fixed frequency PWM scheme also reduces spurious switching noise and ripple to the input power source. The MIC2605/6 is available in an 8-pin 2mm x 2mm MLF® leadless package. This package has an output overvoltage protection feature. Wide input voltage range: 4.5V to 20V Output voltage adjustable to 40V 0.5A switch current and schottky diode MIC2605 operates at 1.2MHz MIC2606 operates at 2MHz Programmable soft start Stable with small size ceramic capacitors High efficiency Low input and output ripple <10µA shutdown current UVLO Output over-voltage and over-temperature protection 8-pin 2mm x 2mm MLF® package –40°C to +125°C junction temperature range The MIC2605/6 has an operating junction temperature range of –40°C to +125°C.
