19-0195; Rev 0; 10/93 MAX750A/MAX758A Adjustable, Step-Down, Current-Mode PWM Regulators _______________General Description The MAX750A/MAX758A are adjustable-output, CMOS, step-down, DC-DC switching regulators. The MAX758A accepts inputs from 4V to 16V and delivers 750m A, while the MAX750A accepts inputs from 4V to 11V and delivers 450m A. Typical efficiencies are 85% to 90%. Typical quiescent current is 1.7m A, or only 6µA in shutdown mode. The output does not exhibit any ripple at subharmonics of the switching frequency over its specified range. Pulse-width-modulation (PWM) current-mode control provides precise output regulation and excellent transient responses. Output voltage accuracy is guaranteed 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 ponents. These regulators require only a...
