♦ 750mA Load Currents (MAX738A/MAX744A)

♦ High-Frequency, Current-Mode PWM

The MAX730A/MAX738A/MAX744A a re 5V-outp ut

CMOS, step-down switching regulators. The MAX738A/

MAX744A accept inputs from 6V to 16V and deliver

750mA. The MAX744A guarantees 500mA load capa-

bility for inputs above 6V and has tighter oscillator fre-

quency limits for low-noise (radio) applications. The

MAX730A accepts inputs between 5.2V and 11V and

delivers 450mA for inputs above 6V. Typical efficien-

c ie s a re 85% to 96%. Quie s c e nt s up p ly c urre nt is

1.7mA and only 6µA in shutdown.

♦ 159kHz to 212.5kHz Guaranteed Oscillator

Frequency Limits (MAX744A)

♦ 85% to 96% Efficiencies

♦ 1.7mA Quiescent Current

♦ 6µA Shutdown Supply Current

Pulse-width modulation (PWM) current-mode control

provides precise output regulation and excellent tran-

sient responses. Output voltage accuracy is guaran-

teed to be ±5% over line, load, and temperature varia-

tions. Fixed-frequency switching allows easy filtering of

output ripple and noise, as well as the use of small

external components. These regulators require only a

single inductor value to work in most applications, so

no inductor design is necessary.

♦ Single Preselected Inductor Value,

No Component Design Required

♦ Overcurrent, Soft-Start, and Undervoltage

Lockout Protection

♦ Cycle-by-Cycle Current Limiting

♦ 8-Pin DIP/SO Packages (MAX730A)

_________________Ord e rin g In fo rm a t io n

The MAX730A/MAX738A/MAX744A also feature cycle-

by-cycle current limiting, overcurrent limiting, undervolt-

age lockout, and programmable soft-start protection.
