Key Features
- Wide 4.5 V to 24 V input range with 3 A continuous output current for versatile power rail applications
- Adjustable output voltage from 0.8 V to 16 V using PWM voltage-mode control for precise regulation
- Compact 6-pin SOT-23 package minimizing board area in space-constrained portable and industrial designs
Applications
The XTPS56339DDCR is designed for point-of-load power regulation in industrial equipment, embedded computing modules, and telecom line cards where a wide input range of 4.5 V to 24 V must be efficiently stepped down to sub-volt or intermediate voltages at up to 3 A. Its compact SOT-23 footprint makes it ideal for space-constrained designs such as smart meters, motor driver boards, and battery-powered IoT nodes. Engineers also use it in automotive accessory circuits and benchtop instruments requiring a fully adjustable output from 0.8 V.

Frequently Asked Questions
What are the input voltage range and maximum output current of XTPS56339DDCR?
The XTPS56339DDCR accepts input voltages from 4.5 V to 24 V and can deliver a continuous output current of up to 3 A, covering a wide range of DC bus voltages found in industrial and consumer electronics power trees.
How low can the output voltage be set on XTPS56339DDCR, and what sets the lower limit?
The output voltage is adjustable from 0.8 V up to 16 V via an external resistor divider; the 0.8 V lower limit is defined by the internal PWM voltage-mode error amplifier reference, enabling sub-1 V rails for FPGAs and memory.
Can XTPS56339DDCR replace a larger SOIC-8 step-down converter to save PCB space?
Yes. The 6-pin SOT-23 package occupies roughly 60% less board area than a standard SOIC-8 outline while offering identical 3 A output capability, making it a drop-in upgrade in density-critical layouts such as wearable device power stages.
