Analog Devices / Maxim Integrated MAXREFDES33 Palo Verde Reference Design

Analog Devices Inc. MAXREFDES33 Palo Verde Step-Down Converter reference design demonstrates the application of the MAX15062A 60V, 300mA ultra-small, high-efficiency, synchronous step-down converter. The reference design operates over a wide 4.5V to 60V input voltage range, and provides up to 300mA at 3.3V output. The device features undervoltage lockout, overcurrent protection, and thermal shutdown. 

The MAX15062A switches at a fixed frequency of 500kHz, and delivers a peak efficiency of 86.77% with the supplied components when the input is 24V. This general-purpose power solution can be used in many different types of power applications, such as 4-20mA current loops, HVAC and building control, high-voltage LDO replacement, general-purpose point-of-load, etc. In this reference design, the MAX15062A performs in 24V input applications, such as industrial sensors, process control, etc.
