Maxim Integrated MAX15026

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. The MAX15026 offers the ability to adjust the switching frequency from 200kHz to 2MHz with an external resistor.

GENERAL DESCRIPTION

FEATURES

♦ 4.5V to 28V or 5V ±10% Input Supply Range ♦ 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 MAX15026 The MAX15026’s adaptive synchronous rectification eliminates the need for an external freewheeling Schottky diode. The device also utilizes the external low-side MOSFET’s on-resistance as a current-sense element, eliminating the need for a current-sense resistor. This protects the DC-DC components from damage during output overloaded conditions or output shortcircuit faults without requiring a current-sense resistor.
