MAX5038 General Description
The MAX5038/MAX5041 dual-phase, PWM controllers provide high-output-current capability in a compact package with a minimum number of external compo- nents. The MAX5038/MAX5041 utilize a dual-phase, average current mode control that enables optimal use of low RDS(ON) MOSFETs, eliminating the need for exter- nal heatsinks even when delivering high output currents.
Differential sensing enables accurate control of the out- put voltage, while adaptive voltage positioning provides optimum transient response. An internal regulator enables operation with input voltage ranges of +4.75V to +5.5V or +8V to +28V. The high switching frequency, up to 500kHz per phase, and dual-phase operation allow the use of low-output inductor values and input capacitor values. This accommodates the use of PC board- embedded planar magnetics achieving superior reliabili- ty, current sharing, thermal management, compact size, and low system cost.
The MAX5038/MAX5041 also feature a clock input (CLKIN) for synchronization to an external clock, and a clock output (CLKOUT) with programmable phase delay (relative to CLKIN) for paralleling multiple phases. The MAX5038 offers a variety of factory-trimmed preset output voltages (see Selector Guide) and the MAX5041 offers an adjustable output voltage from +1.0V to +3.3V. The MAX5038/MAX5041 operate over the extended industrial temperature range (-40°C to +85°C) and are available in a 28-pin SSOP package. Refer to the MAX5037 data sheet for a VRM 9.0 compatible, VID- controlled output voltage controller in a 44-pin MQFP or QFN package.
