Description
The MAX1623 switch-mode buck regulator with synchronous rectification provides local CPU and bus-termination power in notebook and desktop computers.
Features
- constant-off-time, current-mode pulse-width-modulation (PWM) control with switching frequencies as high as 350kHz. An external resistor at the TOFF pin sets the off-time, allowing optimum design flexibility in terms of switching frequency, output switching noise, and inductor size. This device is available in a space-saving 20-pin SSOP package. ____________________________Features
o ±1% Output Accuracy, Including Line and Load Regulation o 94% Efficiency o Internal Switches 55mΩ PMOS Power Swit.
