High-Efficiency, Quad Output, Main Power-Supply Controllers for Notebook Computers

The MAX1777/MAX1977/MAX1999 dual step-down,switch-mode power-supply (SMPS) controllers generatelogic-supply voltages in battery-powered systems. TheMAX1777/MAX1977/MAX1999 include two pulse-widthmodulation (PWM) controllers, adjustable from 2V to 5.5Vor fixed at 5V and 3.3V. These devices feature two linearregulators providing 5V and 3.3V always-on outputs.Each linear regulator provides up to 100mA output cur-rent with automatic linear regulator bootstrapping to themain SMPS outputs. The MAX1777/MAX1977/MAX1999include on-board power-up sequencing, a power-good(PGOOD) output, digital soft-start, and internal soft-stopoutput discharge that prevents negative voltages on shut-down.Maxim’s proprietary Quick-PWM™ quick-response, con-stant on-time PWM control scheme operates WITHOUTsense resistors and provides 100ns response to loadtransients while maintaining a relatively constant switch-ing frequency. The unique ultrasonic pulse-skippingmode maintains the switching frequency above 25kHz,which eliminates noise in audio applications. Other fea-tures include pulse skipping, which maximizes efficiencyin light-load applications, and fixed-frequency PWMmode, which reduces RF interference in sensitive appli-cations.The MAX1777 features a 200kHz/5V and 300kHz/3.3VSMPS for highest efficiency, while the MAX1977 featuresa 400kHz/5V and 500kHz/3.3V SMPS for “thin and light”applications. The MAX1999 provides a pin-selectableswitching frequency, allowing either 200kHz/300kHz or400kHz/500kHz operation of the 5V/3.3V SMPSs, respec-tively. The MAX1777/MAX1977/MAX1999 are available in28-pin QSOP packages and operate over the extendedtemperature range (-40°C to +85°C). The MAX1777/MAX1977/MAX1999 are available in lead-free packages
