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 ...
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 ...
