Overview
MAX8505 6m 19-2992; Rev 1; 9/10 EVAALVUAAILTAIOBNLEKIT 16-QSOP 3A, 1MHz, 1% Accurate, Internal Switch Step-Down Regulator with Power-OK m m x 4.
9m 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.
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.
