General Description
The MAX8505 step-down
regulator operates from a 2.
6V to 5.
5V input and generates an adjustable output voltage from 0.
8V to 0.
85 VIN at up to 3A.
With a 2.
6V to 5.
5V bias supply, the input voltage can be as low as 2.
25V.
The MAX8505 integrates power MOSFETs and operates at 1MHz/500kHz switching frequency to provide a compact design.
Current-mode pulse-widthmodulated (PWM) control simplifies compensation with ceramic or polymer output capacitors and provides excellent transient response.
