Typical Applications
XDPP1140100BXUMA1 is suitable for 6 applications: 48 V Telecom Isolated Bus Converter, Industrial 24 V Input DC-DC Brick, Server Multi-Phase Voltage Regulator Module, Battery-Charging Infrastructure Power Supply, Renewable-Energy Micro-Inverter Auxiliary Supply, Factory-Automation PoE Power Supply.
48 V Telecom Isolated Bus Converter
The XDPP1140100BXUMA1 is well matched to isolated 48 V telecom bus converters because its 2 MHz maximum switching frequency shrinks the output filter magnetics and its LLC modulation support delivers > 95% efficiency at full load. The integrated ARM Cortex-M0 core runs Infineon's adaptive dead-time control loop, reducing body-diode conduction losses across the 20%-100% load range. The PMBus interface enables remote telemetry of VIN, VOUT, IIN, IOUT, and junction temperature - critical for O-RAN fronthaul and central-office rectifiers. Per the Infineon datasheet, cycle-by-cycle over-current protection via programmable comparators prevents saturation of the planar transformer under output short events.
Recommended
Industrial 24 V Input DC-DC Brick
For industrial 24 V nominal input bricks powering factory automation PLCs and motor controllers, the XDPP1140100BXUMA1 offers a wide input range and firmware-programmable control. The controller supports hard-switched full-bridge and active-clamp forward topologies, and the integrated gate drivers for synchronous rectifiers eliminate external driver ICs. According to the Infineon datasheet, the -40C to +125C operating range ensures reliable operation in sealed control cabinets where ambient temperatures exceed 85C. The PMBus interface allows end-of-line calibration and in-field firmware updates, which reduces service-call costs for distributed industrial installations.
Recommended
Server Multi-Phase Voltage Regulator Module
The XDPP1140100BXUMA1 enables compact multi-phase VRM designs for hyperscale servers, where per-phase current sharing and flux balancing are required. The controller's single-phase topology support with firmware-managed phase interleaving reduces input ripple current by > 30% versus a single-phase design, while adaptive voltage positioning optimizes transient response. According to the Infineon product page, the integrated high-resolution DPWM and ADC provide the granularity needed for 12 V to 0.8 V/1.0 V/1.2 V core rails. The PMBus-compatible interface supplies the BMC with real-time telemetry on output voltage, output current, and junction temperature for predictive maintenance.
Recommended
Battery-Charging Infrastructure Power Supply
In Level-2 EV charger and energy-storage system power supplies, the XDPP1140100BXUMA1's programmable control loop adapts to Li-ion charge profile curves (CC/CV) and supports firmware-driven safety shutoff on over-voltage or over-temperature events. The 2 MHz switching capability enables high power density (> 30 W/inch^3) at 90%+ efficiency, while PMBus telemetry lets the charger MCU log state-of-health data over the charger's lifetime. Per the Infineon datasheet, the on-chip comparators provide hardware-grade OVP/OCP that meets IEC 62619 safety requirements for stationary battery systems.
Recommended
Renewable-Energy Micro-Inverter Auxiliary Supply
Solar micro-inverter auxiliary power supplies benefit from the XDPP1140100BXUMA1's wide operating temperature range and firmware programmability. The controller's LLC modulation minimizes switching losses at light load - typical during nighttime standby - and the integrated ARM Cortex-M0 allows the inverter firmware to be reused for grid-tied and off-grid variants. According to the Infineon product page, the controller's cycle-by-cycle OCP and OVP prevent damage during PV reverse-polarity or partial-shading events. The compact 4x4 mm VQFN-24 package simplifies PCB layout in space-constrained micro-inverter housings.
Recommended
Factory-Automation PoE Power Supply
In Power-over-Ethernet (PoE++) power supplies for factory automation switches and IP cameras, the XDPP1140100BXUMA1 drives the isolated DC-DC stage that converts 48-57 V PoE input to 12 V or 5 V outputs. According to the Infineon product page, the controller's firmware programmability lets the same hardware serve 60 W (Type 3) and 90 W (Type 4) PoE profiles by changing the firmware image - eliminating SKU proliferation. Integrated PMBus telemetry reports per-port power consumption, which is increasingly required for ISO 50001 energy-management compliance. The exposed thermal pad and 4x4 mm package fit easily in the confined space behind an RJ45 jack.

Design Notes
Solder the exposed thermal pad (pin 24) of the PG-VQFN-24-20 package to a continuous, uninterrupted ground copper pour that extends at least 25 mm^2 under and around the package. Use thermal vias (8-12, 0.3 mm drill) to tie the top-pour to inner ground planes. Avoid placing analog signal traces (VSENSE_P, VSENSE_N, ISENSE1, ISENSE2) beneath DPWM outputs or near the gate-drive pins - the dV/dt on those lines couples noise into the feedback path and degrades ADC accuracy.
Provide a low-impedance 3.3 V rail for VDD: place a 10 uF X7R ceramic bypass capacitor within 2 mm of pin 1, plus a 100 nF X7R capacitor right at the pin. Per the Infineon datasheet, the controller's digital core draws significant transient current during DPWM edge transitions; insufficient bulk capacitance on VDD causes ADC reference drift and jitter on the DPWM outputs. If the upstream 3.3 V LDO is shared with other ICs, isolate it with a ferrite bead.
Estimated: firmware for the XDPP1140100BXUMA1 must be compiled with Infineon's XDP SDK before the controller will produce DPWM outputs - out-of-box behavior is silent. Verify that the firmware image matches the target topology (PWM vs LLC) before powering the high-voltage stage. Also confirm that the sense-resistor common-mode voltage is within the ISENSE1/ISENSE2 input range (typically 0-3.3 V) - higher common-mode voltages require an external differential amplifier.
Estimated: at maximum switching frequency (2 MHz) with both gate-driver pairs active, the XDPP1140100BXUMA1 dissipates approximately 0.5 W from the VDD supply. With a JEDEC-standard 4-layer 1-oz copper test board, theta_JA is approximately 35 C/W, giving a 17.5 C temperature rise above ambient. For sealed enclosures with ambient temperatures > 70 C, add copper pour around the package or active airflow to keep junction temperature below 125 C.
Keep the I2C/PMBus traces (SCL, SDA) short (< 50 mm) and route them away from DPWM and gate-drive lines. Place 4.7 kohm pull-up resistors on SCL and SDA close to the controller. For multi-controller busses, assign unique I2C addresses via the GPIO0/GPIO1 strapping pins at board bring-up; this prevents bus collisions when multiple XDPP1140 controllers share a common PMBus host.
