MAX5037A VRM 9.0/VRM 9.1, Dual-Phase, Parallelable, Average-Current-Mode Controller

The MAX5037A dual-phase, PWM Controller provides high-output-current capability in a compact package with a minimum number of external components. The MAX5037A utilizes a dual-phase, average-current-mode control that enables optimal use of low RDS(ON) MOSFETs eliminating the need for external heatsinks even when delivering high output currents.
Differential sensing enables accurate control of the output voltage, while adaptive voltage positioning provides optimum transient response. An internal regula-tor enables operation with either +5V or +12V input volt-age without the need for additional voltage sources. The high switching frequency, up to 500kHz per phase, and dual-phase operation allow the use of low output induc-tor values and input capacitor values. This accommo-dates the use of PC board-embedded planar magnetics achieving superior reliability, current sharing, thermal management, compact size, and low system cost.
The MAX5037A also features 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 MAX5037A also limits the reverse current in case the bus voltage becomes higher than the regulated output voltage.
The MAX5037A operates over the extended temperature range (-40C to +85C) and is available in 44-pin MQFP or thin QFN packages. Refer to the MAX5038A MAX5041A and MAX5065 MAX5067 data sheets for either a fixed output voltage controller or an adjustable output voltage controller in an SSOP or thin QFN package.
