Microchip Technology offers a 2MHz, 500mA switching regulator. This switching regulator provides features starting from adjustable and fixed output voltages under voltage lockout to an automatic mode transition from pulse-width modulation [PWM] to pulse-frequency modulation [PFM]. The MCP1603 have significant features like small footprint and high efficiency [90 per cent], which are essential to the rapidly growing handheld and battery-operated device market.
