Additional preview pages of the MAX744A datasheet.

The MAX730A/MAX738A/MAX744A are 5V-output CMOS, step-down switching regulators.

The MAX738A/ MAX744A accept inputs from 6V to 16V and deliver 750mA.

The MAX744A guarantees 500mA load capability for inputs above 6V and has tighter oscillator frequency limits for low-noise (radio) applications.

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 Overcurrent, Soft-Start, and Undervoltage Lockout Protection o Cycle-by-Cycle Current Limiting o 8-Pin DIP/SO Packages (MAX730A) _________________Ordering Information PART TEMP.
