ADI multi-phase boost controller

Zhengzhou4周前Digital125

The MAX25203 features both programmable gate drive voltage and current limit blanking time, as well as accurate current balancing, and operates at a high switching frequency to reduce the bill of materials cost and shrink PCB space by 36%.

The controller starts with a battery input voltage from 4.5V to 42V and operates down to 1.8V after start-up.

It sustains an absolute maximum output voltage of up to 70V and features a low shutdown supply current of 5µA.

Useful to generate backlight and Class-D audio amplifier voltages, the device offers I²C bus diagnostics including die temperature, phase current monitoring and optional true shutdown to improve system reliability.

Output voltage is scalable via the PWM input or I²C interface and a sync-out feature supports additional phases for higher power systems.

Key Features

Factory programmable gate drive voltage from 5.5V to 10V increases power density by reducing MOSFET RDS(on) loss for higher efficiency and lower cost.

 Programmable current limit blanking time supports short peak current events without power supply overdesign for lower solution cost. ±5 percent current share accuracy from phase-to-phase reduces inductor size. Resistor programmable switching frequency up to 2.1 MHz improves EMI and reduces external components’ size and count. The MAX25203 is available as of now in a 32-Lead TQFN-CU packaging. The MAX25203EVKIT Evaluation Board is also available as of now. Download data sheet, order samples and evaluation boards: https://bit.ly/MAX25203Product Connect with ADI digital isolation experts on EngineerZone™, an engineering community forum: https://ez.analog.com/interface-isolation
