Maxim Integrated MAX15023

The MAX15023 dual, synchronous step-down controller operates from a 5.5V to 28V or 5V ±10% input voltage range and generates two independent output voltages. Each output is adjustable from 85% of the input voltage down to 0.6V and supports loads of 12A or higher. The MAX15023 offers the ability to adjust the switching frequency from 200kHz to 1MHz with an external resistor.

FEATURES

5.5V to 28V or 5V ±10% Input Supply Range 0.6V to (0.85 x VIN) Adjustable Outputs Adjustable 200kHz to 1MHz Switching Frequency Guaranteed Monotonic Startup into a Prebiased Load Lossless, Cycle-by-Cycle, Low-Side, Source Peak Current Limit with Adjustable, TemperatureCompensated Threshold Cycle-by-Cycle, Low-Side, Sink Peak CurrentLimit Protection Proprietary Adaptive Internal Digital Soft-Start ±1% Accurate Voltage Reference Internal Boost Diodes Adaptive Synchronous Rectification Eliminates External Freewheeling Schottky Diodes Hiccup-Mode Short-Circuit Protection and Thermal Shutdown Power-Good Outputs and Analog Enable Inputs for Power Sequencing MAX15023 Input voltage ripple and total RMS input ripple current are reduced by interleaved 180° out-of-phase operation. The MAX15023’s adaptive synchronous rectification eliminates the need for external freewheeling Schottky diodes. 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.
