DC6M502X6

DC6M50xX6 family 6 MHz, 500 mA, ultra small DC-to-DC buck converter Rev. 1 — 13 February 2013 Product data sheet 1. Product profile 1.1 General description The DC6M50xX6 family consists of highly efficient 6 MHz, 500 mA step-down DC-to-DC converters. The devices convert input voltages between 2.3 V and 5.5 V to fixed output voltages of 1.2 V, 1.5 V or 1.8 V. The devices of DC6M50xX6 family are optimized for battery-driven applications. Their high efficiency of up to 95 % enables an extended battery life in all portable designs. Buck operation at a switching frequency of 6 MHz allows using only a small low-cost 470 nH coil and two capacitors. Besides working with standard chip inductors, the DC6M50xX6 family devices also support Printed-Circuit Board (PCB) coils and air coils. Product versions with and without automatic mode selection between Pulse Frequency Modulation (PFM) and Pulse Width Modulation (PWM) are available. Optionally the devices can be switched to forced PWM mode....
