♦ Up to 750mA Load Currents

The MAX750A/MAX758A are adjustable-output, CMOS,

s te p -d own, DC-DC s witc hing re g ula tors . The

MAX758A accepts inputs from 4V to 16V and delivers

750mA, while the MAX750A accepts inputs from 4V to

11V and delivers 450mA. Typical efficiencies are 85%

to 90%. Typical quiescent current is 1.7mA, or only

6µA in shutdown mode. The output does not exhibit

any ripple at subharmonics of the switching frequency

over its specified range.

♦ 160kHz High-Frequency, Current-Mode PWM

♦ 85% to 96% Efficiencies

♦ 33µH or 100µH Pre-Selected Inductor Value,

No Component Design Required

♦ 1.7mA Quiescent Supply Current

♦ 6µA Shutdown Supply Current

♦ Adjustable Output Voltage

Pulse-width-modulation (PWM) current-mode control

provides precise output regulation and excellent tran-

sient responses. Output voltage accuracy is guaran-

teed to be ±4.5% plus feedback-resistor tolerance over

line, load, and temperature variations. Fixed-frequency

switching and absence of subharmonic ripple 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.

♦ Overcurrent, Soft-Start, and Undervoltage

Lockout Protection

♦ Cycle-by-Cycle Current Limiting

♦ 8-Pin DIP/SO Packages (MAX750A)
