MAX15026BATD Datasheet

Low-Cost, Small, 4.5V to 28V Wide Operating Range, DC-DC Synchronous Buck Controller


General Description
The MAX15026 synchronous step-down controller operates from a 4.5V to 28V input voltage range and generates an adjustable output voltage from 85% of the input voltage down to 0.6V while supporting loads up to 25A. The device allows monotonic startup into a prebiased bus without discharging the output and features adaptive internal digital soft-start.

♦ 0.6V to (0.85 x VIN) Adjustable Output
♦ Adjustable 200kHz to 2MHz Switching Frequency
♦ Ability to Start into a Prebiased Load
♦ Lossless, Cycle-by-Cycle Valley Mode Current Limit with Adjustable, Temperature-Compensated Threshold
♦ Sink-Mode Current-Limit Protection
♦ Adaptive Internal Digital Soft-Start
♦ ±1% Accurate Voltage Reference
♦ Internal Boost Diode
♦ Adaptive Synchronous Rectification Eliminates External Freewheeling Schottky Diode
♦ Hiccup-Mode Short-Circuit Protection
♦ Thermal Shutdown
♦ Power-Good Output and Enable Input for Power Sequencing
♦ ±5% Accurate Enable Input Threshold
♦ AEC-Q100 Qualified (MAX15026B)
