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-width modulated (PWM) control simplifies compensation with ceramic or polymer output capacitors and provides excellent transient response.
The MAX8505 features 1% accurate output over load, line, and temperature variations.
Adjustable soft-start is achieved with an external capacitor.
During the soft-start period, the voltage-regulation loop is active.
This limits the voltage dip when the active devices, such as microprocessors or ASICs connected to the MAX8505’s output, apply a sudden load current step upon passing their undervoltage thresholds.
The MAX8505 features current-limit, short-circuit, and thermal-overload protection and enables a rugged design.
Open-drain power-OK (POK) monitors the output voltage.
