The MAX5038/MAX5041 dual-stage, PWM controllers provide high output current capability in a compact package with minimal external component count. The MAX5038/MAX5041 utilize dual-phase, average-current-mode control, enabling optimal use of low RDS(ON) MOSFETs, without the need for an external heat sink even when delivering high output currents. Differential sensing technology can precisely control the output voltage, and adaptive voltage positioning provides the best transient response. An internal voltage regulator with an input voltage range of +4.75 V enables operation from +5.5 V or 8 V to +28 V. High switching frequency, 500kHz per phase and dual phase operation allows the use of low output inductor values and input capacitor values. This is suitable for use with PC board-embedded planar magnetics for superior reliability, current sharing, thermal management, compact size, and low system cost. The MAX5038/MAX5041 also feature a clock input (CLKIN) to synchronize multiple stages to an external clock and a programmable phase delay of the clock output (CLKOUT) (relative to CLKIN). The MAX5038 offers various factory-trimmed preset output voltages (see the Selection Guide) and the MAX5041 offers an adjustable output voltage from +1.0 V to 3.3 V. The MAX5038/MAX5041 operate over the extended industrial temperature range (-40°C to +85°C) and are available in a 28-pin SSOP package. See the MAX5037 datasheet for a VRM9.0 compatible, VIDcontrolled output voltage controller in a 44-pin MQFP or QFN package.
