Figure 1: In a step-up converter, all you have to do to change the output voltage is change the duty cycle of the switching signal. Interestingly, the circuit raises the voltage by changing the duty ...
From Maxim Integrated Products, the MAX8569A and MAX8569B are step-up dc-dc converters with a built-in synchronous rectifier and up to 95% efficiency. The converters consume only 7 µA of quiescent ...
Housed in 8-pin TDFN packages, the 36-V MAX8595/6 step-up dc/dc converters power up to eight LEDs in series at 25 mA. Features include a 1-MHz PWM switching frequency, up to 86% efficiency, a 12-mVp-p ...
A hybrid DC-DC converter topology boosts efficiency by combining a buck regulator and a charge pump. Is it the future of intermediate bus conversion?
