Product details
Overview
IP1201TRPBF from Infineon Technologies is a dual-output, 2-phase synchronous buck power block integrating power MOSFETs, PWM controller, gate drivers, and passive components in a single module. It delivers up to 15A per output (30A total in single-output mode), supports 3.14–5.5V input and 0.8–3.3V programmable output, operates at 200–400kHz per phase with 180° phase shift, and includes independent soft-start, overvoltage/overcurrent/overtemperature protection - used in high-density server VRMs and telecom POL converters.
For engineers reviewing the IP1201TRPBF datasheet, IP1201TRPBF pinout, IP1201TRPBF application, or IP1201TRPBF equivalent, key selection criteria include dual-phase current sharing accuracy, thermal derating at 125°C block temperature, external synchronization capability up to 800kHz, and hiccup vs. latch overcurrent response configuration via the HICCUP pin.
Technical Context
The IP1201TRPBF implements a two-phase interleaved synchronous buck architecture with integrated high- and low-side MOSFETs per phase, internal current-mode PWM control, and independent error amplifiers for each output. Its 180° phase shift reduces input/output ripple and improves transient response while enabling compact filter design.
It features a programmable switching frequency (200–400kHz per channel via RT resistor), external sync input (480–800kHz), and dual feedback loops with 0.8V reference voltage, ±2.5% output accuracy over temperature, and 25µA FB bias current - supporting precise point-of-load regulation in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.14V to 5.5V - supports standard 3.3V and 5V intermediate bus architectures without external pre-regulation. |
| Output Voltage Range | 0.8V to 3.3V - programmable via external resistive divider; compatible with DDR, FPGA, ASIC core, and I/O rail requirements. |
| Max Output Current | 15A per channel (dual output) or 30A combined (single output) - enables high-current POL delivery in space-constrained layouts. |
| Switching Frequency | 200–400kHz per channel - adjustable via RT resistor; allows optimization of efficiency vs. size trade-off with standard 1.8µH inductors. |
| Thermal Limit | 125°C block temperature - specified safe operating area validated up to 125°C ambient with no heatsink or airflow. |
| Protection Features | Hiccup or latch overcurrent, overvoltage (1.15×VOUT), undervoltage lockout (2.7V), and thermal shutdown (140°C) - ensures robust system-level fault containment. |
| Soft Start | Independent SS1/SS2 pins with 5ms typical time (0.1µF capacitor) - prevents inrush current and enables staggered rail sequencing. |
Pinout & Package
IP1201TRPBF is housed in a thermally enhanced, leadless QFN-style module measuring 15.5mm × 9.25mm × 2.6mm with exposed thermal pad (PGND-connected) and 36-pin perimeter terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Primary input power supply | Accepts 3.14–5.5V; connects to bulk capacitance and must be decoupled locally per phase. |
| VOUT1 / VOUT2 | Output power terminals | Deliver regulated DC; each supports up to 15A RMS; require dedicated output capacitors and inductor connections. |
| FB1 / FB2 | Feedback inputs | Resistive divider nodes for closed-loop regulation; 0.8V reference; 25µA bias current affects divider design. |
| SS1 / SS2 | Soft-start control | Capacitor-based timing; 0.25V threshold disables output; enables controlled ramp-up per rail. |
| HICCUP | Overcurrent response select | Pulled low = latch-off; pulled high = hiccup mode; sets fault recovery behavior during short-circuit events. |
| SYNC | External clock input | Accepts 480–800kHz square wave; synchronizes switching to avoid beat frequencies in multi-module systems. |
| PGOOD | Power-good indicator | Open-drain output asserting when both outputs are within ±10% of target; sinks 2mA at 0.25V low. |
| ENABLE | Global enable input | Active-high logic; 2V min high threshold; UVLO active below 2.7V VIN ensures clean startup. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent outputs | Each output fully configurable (VOUT, soft-start, OVP threshold), enabling asymmetric rail generation (e.g., 1.2V core + 2.5V I/O). |
| Integrated passives & MOSFETs | Eliminates discrete power stage layout sensitivity; reduces BOM count by >12 components versus controller+MOSFET solution. |
| 180° interleaved operation | Halves input ripple current and doubles effective switching frequency - cuts required input capacitance by ~50%. |
| Thermal-aware SOA | Derated current curves provided up to 125°C block temperature; enables reliable operation in sealed enclosures without forced air. |
| External sync & RT programming | Supports deterministic timing across multiple modules and fine-tuned efficiency optimization across load and input conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output synchronous buck power block applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2960GQ-Z (Monolithic Power) | Single-chip dual-output controller (no integrated MOSFETs); requires external power stage; 4.5–16V input. | Higher design flexibility but larger PCB area and greater layout sensitivity; suited for custom thermal solutions. | Select when board space allows discrete power stage and input exceeds 5.5V. |
| TPS546D24 (Texas Instruments) | Single-output, 60A capable digital multiphase controller; supports PMBus; no integrated MOSFETs or passives. | Requires external DrMOS or power stages; targets high-end server CPUs with dynamic phase shedding and telemetry. | Select when digital control, telemetry, or >30A single-rail output is required. |
Compared with MP2960GQ-Z and TPS546D24, the IP1201TRPBF offers lowest component count and smallest footprint for ≤30A dual-rail applications, trading off programmability and telemetry for integration density and thermal simplicity.

FAQ
What is the maximum recommended PCB temperature for continuous 15A per channel operation?
The IP1201TRPBF supports 15A per channel continuously at up to 125°C block temperature, as verified in Figure 3 of the datasheet. At 90°C PCB temperature with no airflow or heatsink, derating to 11.5A per channel applies. Thermal design must ensure the exposed thermal pad is soldered to a minimum 4-layer PCB with ≥200mm² copper pour and ≥4 thermal vias.
Can IP1201TRPBF operate with only one output enabled?
Yes - the device supports single-output mode by connecting VOUT1 and VOUT2 together and configuring FB1/FB2 as a single feedback node. In this configuration, it delivers up to 30A total with full 2-phase interleaving. The unused SS2 and FB2 pins must be tied to their respective VOUT or grounded per datasheet Section 8.2.1.
How does the HICCUP pin affect overcurrent protection behavior?
When HICCUP is pulled high, the device enters hiccup mode: it shuts down for ~10ms after overcurrent detection, then retries. When pulled low, it latches off until ENABLE is cycled. This pin directly configures fault recovery - hiccup mode suits intermittent faults (e.g., hot-swap transients), while latch mode suits permanent shorts requiring manual reset.
Is external compensation required for stable loop operation?
No external compensation is required - the IP1201TRPBF integrates type-II compensation networks for both channels. Stability is ensured across the full output voltage (0.8–3.3V) and load (0–15A) range with standard 1.8µH inductors and recommended output capacitor ESL/ESR values listed in Table 10 of the datasheet.
