Maxim MAX8734AEEI+

电源控制器4.5V ~ 24V25 µA

Overview

The MAX8732/MAX8733/MAX8734AEEI dual step-down, switch-mode power-supply (SMPS) controllers generate logic-supply voltages in battery-powered systems. The MAX8732/MAX8733/MAX8734AEEI include two pulse-width modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V. These devices feature two linear regulators providing 5V and 3.3V always-on outputs.

♦No Current-Sense Resistor Needed (MAX8734) ♦Accurate Current Sense with Current-Sense Resistor (MAX8732/MAX8733) ♦1.5% Output Voltage Accuracy ♦3.3V and 5V 100mA Bootstrapped Linear Regulators ♦Internal Soft-Start and Soft-Stop Output Discharge ♦Quick-PWM with 100ns Load Step Response ♦3.3V and 5V Fixed or Adjustable Outputs(Dual Mode™) ♦4.5V to 24V Input Voltage Range ♦Enhanced Ultrasonic Pulse-Skipping Mode(25kHz min) ♦Power-Good (PGOOD) Signal ♦Overvoltage Protection Enable/Disable
