Overview

The MAX735 and MAX755 are CMOS, inverting switchmode regulators with internal power MOSFETs. The MAX755 operates from a +2.7V to +9V input and generates an adjustable negative output; 1W output power is guaranteed when powered from a +4.5V input. The MAX735 operates from a +4.0V to +6.2V output; 200mA output current is guaranteed for inputs greater than +4.5V. Quiescent supply current for the MAX735 is typically 1.6mA, and a shutdown mode reduces this to 10μA. These power conserving features, along with high efficiency and applications circuits that lend themselves to miniaturization, make the MAX735/MAX755 excel in a broad range of on-card and portable-equipment applications. The MAX735/MAX755 employ a high-performance current mode pulse-width modulation (PWM) control scheme to provide tight output-voltage regulation and low subharmonic noise. The fixed-frequency oscillator is factory trimmed to 160kHz, allowing for easy noise filtering. The regulators are production tested in actual application circuits, and output accuracy is guaranteed to within ±5% over all specified conditions of line, load, and temperature. The input-to-output differential of the MAX755 is limited to VIN + |VOUT| ≤ 11.7V. The MAX735/MAX755 are monolithic CMOS ICs containing a current-mode PWM controller and a 2A P-channel power MOSFET. Current-mode control provides excellent line-transient response, inherent overcurrent protection, and excellent AC stability. The switch transistor is a current-sensing MOSFET that splits off a fraction of the total source current for current-limit detection.
