MAX8723 - Step-Down Regulator

General Description

The MAX8723 is a high-efficiency, switch-mode, stepdown regulator with a 14V internal power switch.

With only a few external passive components, this low-cost regulator can generate a fixed 3.3V or adjustable DC output voltage of 2.0V to 3.6V of 2.0V to 3.6V (dual mode) from a 6V to 13.2V DC source.

Key Features

  • an internal power MOSFET, a built-in bootstrap diode for its MOSFET driver, and an interface for an external synchronous rectifier MOSFET drive to replace the Schottky diode and improve efficiency. Its fixed-frequency PWM/skip-mode operation and current-mode control architecture provide fast load-transient response without compensation. The switching frequenc.

MAX8723 19-3949 Rev 0; 4/06 EVAALVUAAILTAIOBNLEKIT Low-Cost, Internal-Switch, Step-Down Regulator for LCD Displays General Description The MAX8723 is a high-efficiency, switch-mode, stepdown regulator with a 14V internal power switch. With only a few external passive components, this low-cost regulator can generate a fixed 3.3V or adjustable DC output voltage of 2.0V to 3.6V of 2.0V to 3.6V (dual mode) from a 6V to 13.2V DC source. The 13.2V input voltage range makes this part ideal for LCD displays, point-of-load regulators, and other 8/12V-powered industrial equipment applications. The MAX8723 can deliver up to 2A.
