Microchip Technology, Inc. 1.2 MHz 0.8A Isw Wide Input Range Boost Regulator w/ Integrated Schottky MIC2605

The MIC2605/6 is a 1.2MHz/2MHz, PWM DC/DC boost switching regulator. 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 has an operating junction temperature range of -40°C to +125°C. Additional Features Wide input voltage range: 4.5V to 20V Output voltage adjustable to 40V 0.5A (min) / 0.8A(typ) 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 -40°C to +125°C junction temperature range
