Abstract
This paper presents a PWM controlled buck DC-DC converter. Switching frequency is up to 10 MHz and optimized output voltages are 0.65 V, 0.9 V and 1.2 V. At maximum switching frequency the DC-DC converter presents an efficiency of 73% with a current load of 300 mA and 0.9 V as output and 78% for the same load current and 1.2 V as output voltage both from 3.6 V input voltage. Average ripple is lower than 18 mV for both outputs.
