Key Features
- Wide 4 V to 36 V input range covering automotive, industrial 24 V, and 12 V systems in a single device
- 600 mA synchronous step-down output with integrated MOSFET eliminating external rectifier diode and reducing power loss
- Current-mode PWM control providing fast load transient response and simplified compensation design
- Tiny SOT-23-6 package enabling high-density point-of-load power conversion on space-constrained boards
Applications
The XTPS560430XFDBVR is used as a point-of-load regulator in industrial 24 V systems, automotive accessory modules, and distributed power architectures where a wide-input, compact step-down converter must supply logic rails at up to 600 mA. Its 4 V to 36 V input range makes it suitable for stepping down automotive battery voltages to 3.3 V or 5 V for microcontrollers and sensors. Engineers also deploy it in building automation controllers and IoT gateway boards where PCB space is limited and a SOT-23-6 footprint minimizes the power stage area.

Frequently Asked Questions
What input voltage range does XTPS560430XFDBVR support and what maximum output current does it deliver?
The XTPS560430XFDBVR accepts input voltages from 4 V to 36 V and delivers a maximum continuous output current of 600 mA, covering automotive 12 V and 24 V industrial supply rails while providing adequate current for microcontrollers, sensors, and communication ICs.
How does the synchronous rectification in XTPS560430XFDBVR improve efficiency over non-synchronous alternatives?
Synchronous rectification replaces the external catch diode with an integrated low-side MOSFET, reducing the voltage drop from roughly 0.4 V to under 0.1 V at 600 mA load, which improves conversion efficiency by several percentage points and reduces heat dissipation in the compact SOT-23-6 package.
For a 24 V industrial sensor node, how does XTPS560430XFDBVR simplify the power design compared to a LDO regulator?
An LDO dropping 24 V to 3.3 V at 600 mA would dissipate over 12 W as heat, requiring a heatsink and large PCB copper pour. The XTPS560430XFDBVR switching converter maintains high efficiency across that range, typically above 80%, reducing thermal burden to under 2 W and fitting the entire power stage into a SOT-23-6 footprint.
What control mode does XTPS560430XFDBVR use, and how does that affect loop compensation?
The device uses current-mode PWM control, which inherently limits peak inductor current for cycle-by-cycle overcurrent protection and simplifies the feedback loop compensation to a single output capacitor and resistor divider, reducing design time and external component count compared to voltage-mode control topologies.
