Features

* o 750mA Load Currents (MAX738A/MAX744A) o High-Frequency, Current-Mode PWM o 159kHz to 212.5kHz Guaranteed Oscillator Frequency Limits (MAX744A) o 85% to 96% Efficiencies o 1.7mA Quiescent Current o 6µA Shutdown Supply Current o Single Preselected Inductor Value, No Component Design Required o Overc

Applications

* The MAX730A accepts inputs between 5.2V and 11V and delivers 450mA for inputs above 6V. Typical efficiencies are 85% to 96%. Quiescent supply current is 1.7mA and only 6µA in shutdown. Pulse-width modulation (PWM) current-mode control provides precise output regulation and excellent transient respo
