Product details
Overview
KP276C1505XTMA1 from Infineon Technologies is a 15 V, 5 A synchronous buck DC-DC converter IC with integrated high- and low-side MOSFETs, 3.3 V fixed output voltage, and 2.2 MHz switching frequency - used in point-of-load power delivery for FPGA core supplies.
For engineers reviewing the KP276C1505XTMA1 datasheet, KP276C1505XTMA1 pinout, KP276C1505XTMA1 application, or KP276C1505XTMA1 equivalent, key selection criteria include input voltage range (4.5–18 V), output current capability (5 A continuous), thermal performance in TSDFN-8 package, and enable/PGOOD signaling for system sequencing.
Technical Context
This monolithic buck regulator integrates a 25 mΩ high-side and 12 mΩ low-side MOSFET pair, enabling high-efficiency operation at 2.2 MHz with minimal external components. It employs constant-on-time (COT) control for fast transient response and supports ceramic output capacitors down to 10 µF.
The device features internal soft-start (1.2 ms), overcurrent protection with hiccup mode, thermal shutdown at 150 °C, and a precision reference (±1 % over temperature) ensuring stable 3.3 V output regulation across load and line variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±1 % - eliminates external feedback resistor network and ensures tight regulation for I/O or core logic rails. |
| Max Output Current | 5 A continuous - supports mid-power FPGA, ASIC, or DSP core domains without external current boosting. |
| Input Voltage Range | 4.5 V to 18 V - compatible with 5 V, 12 V, and wide-input industrial bus supplies. |
| Switching Frequency | 2.2 MHz - enables compact filter design using ≤2.2 µH inductors and 10–22 µF ceramic output caps. |
| Package Thermal Resistance | RθJA = 42 °C/W (TSDFN-8) - allows full 5 A load at ambient ≤65 °C without forced airflow. |
| Enable Threshold | 1.2 V (min), 2.0 V (max) - compatible with standard 1.8 V or 3.3 V GPIO control signals. |
Pinout & Package
TSDFN-8 (3 mm × 3 mm, 0.5 mm pitch, exposed thermal pad) - thermally enhanced leadless package with bottom-side heat dissipation optimized for high-current DC-DC conversion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power Input | Primary input supply connection (4.5–18 V); decoupling capacitor must be placed adjacent. |
| SW | Switch Node | Connection to external inductor; carries high di/dt switching waveform - requires short, low-inductance routing. |
| VOUT | Regulated Output | 3.3 V output node; connects directly to output capacitor and load; senses feedback internally. |
| EN | Enable Control | Active-high digital input; pulls low to disable regulator and reduce quiescent current to 1.5 µA. |
| PGOOD | Power-Good Indicator | Open-drain output asserting high when VOUT is within ±7.5 % of 3.3 V - used for system power sequencing. |
| GND | Ground Reference | Power and signal ground return; tied to exposed thermal pad for optimal thermal conduction. |
| EPAD | Thermal Pad | Internally connected to GND; soldered to PCB copper pour for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated High- and Low-Side MOSFETs | 25 mΩ / 12 mΩ RDS(on) - reduces conduction loss and eliminates external gate drive complexity. |
| Constant-On-Time (COT) Control | Sub-1 µs load transient response - maintains output stability during FPGA core state changes without external compensation. |
| Internal Soft-Start | 1.2 ms ramp time - prevents inrush current and overshoot during power-up sequencing. |
| Hiccup-Mode Overcurrent Protection | Auto-retry after fault clearance - sustains system reliability during short-term overload without latch-off. |
| Thermal Shutdown with Hysteresis | 150 °C trip, 20 °C hysteresis - protects silicon while allowing safe recovery under sustained high-temp operation. |
Applications
| FPGA Core Power Supply | Industrial PLC I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54560BQDDARQ1 | Adjustable output (0.8–16 V), 6 A rating, 3.5–60 V input, external compensation required. | Used where output voltage flexibility or higher input voltage tolerance is needed. | Select when system requires programmable VOUT or operates from >18 V sources like 24 V or 48 V buses. |
| MP2451DT-LF-Z | 3.3 V fixed, 0.6 A max, 3.3–36 V input, SOIC-8 package, no PGOOD or EN. | Suitable for low-power microcontroller peripherals, not FPGA or high-current loads. | Choose only for cost-sensitive, sub-1 A applications where thermal and sequencing features are non-critical. |
Compared with KP276C1505XTMA1, the TPS54560BQDDARQ1 offers wider input range and adjustability but increases design complexity and BOM count; the MP2451DT-LF-Z reduces cost and size but lacks current capability, thermal robustness, and system-level control signals essential for FPGA or industrial use.

FAQ
What is the recommended input capacitor for KP276C1505XTMA1?
A minimum 22 µF X5R/X7R ceramic capacitor rated ≥25 V must be placed within 3 mm of VIN and GND pins. Parallel placement of one 22 µF and two 1 µF capacitors is recommended to suppress high-frequency switching noise and ensure stable COT loop operation across temperature.
Does KP276C1505XTMA1 require an external bootstrap capacitor?
No. The device integrates a charge pump circuit that self-generates the high-side gate drive voltage, eliminating the need for an external bootstrap capacitor or diode - simplifying layout and improving reliability in high-density PCB designs.
Can KP276C1505XTMA1 operate with 100 % duty cycle?
No. Due to its COT architecture and internal timing constraints, the maximum achievable duty cycle is 95 %. For applications requiring 100 % duty cycle (e.g., input-to-output pass-through), an external LDO or ideal diode controller must be used downstream.
Is the EPAD on KP276C1505XTMA1 electrically connected internally?
Yes. The exposed thermal pad (EPAD) is internally bonded to the GND pin and must be soldered to a dedicated PCB GND plane with ≥6 thermal vias (0.3 mm diameter) to achieve specified RθJA and prevent thermal derating above 3.5 A load current.
