Product details
Overview
IP1202TRPBF from Infineon Technologies is a dual-output, 2-phase synchronous buck power block integrating power MOSFETs, PWM controllers, gate drivers, and passive components in a single 15.5 mm × 9.25 mm × 2.6 mm package. It delivers up to 15 A per channel (30 A total in dual-phase mode), supports 0.8 V–5.0 V output voltage range, operates at 200–400 kHz per channel, and features independent soft-start, overvoltage/overcurrent/overtemperature protection - used in high-density server VRMs and telecom POL converters.
For engineers reviewing the IP1202TRPBF datasheet, IP1202TRPBF pinout, IP1202TRPBF application, or IP1202TRPBF equivalent, key selection criteria include per-channel current capability (15 A RMS), dual-phase 180° interleaving for ripple cancellation, external synchronization support (480–800 kHz), hiccup-mode overcurrent response, and integrated thermal sensing with 140°C shutdown threshold.
Technical Context
The IP1202TRPBF implements a two-phase interleaved synchronous buck architecture with independent error amplifiers, dual ramp oscillators, and phase-shifted PWM generation. Each channel includes dedicated FB, SS, OCSET, and PGOOD pins, enabling precise voltage regulation and current sharing across outputs.
It integrates high- and low-side MOSFETs with optimized RDS(on) and gate drive circuitry, eliminating discrete driver design complexity. The internal 0.8 V reference, ±3% output accuracy over temperature, and 25 µA FB bias current support tight regulation in multi-rail systems requiring dynamic load step response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 5.5 V to 13.2 V - supports 5 V, 12 V intermediate bus architectures without external pre-regulation. |
| Output Voltage Range | 0.8 V to 5.0 V - programmable via external resistor divider; compatible with core logic, memory, and I/O rails. |
| Max Output Current | 15 A per channel (30 A combined) - enables compact dual-rail POL conversion with minimal PCB area. |
| Switching Frequency | 200–400 kHz per channel - adjustable via RT resistor; balances efficiency, size, and EMI performance. |
| Thermal Shutdown | 140 °C - internal die temperature sensing ensures reliable operation under sustained overload or airflow loss. |
| Soft Start Time | 5 ms (with 0.1 µF capacitor) - prevents inrush current during power-up of sensitive downstream loads. |
| PGOOD Threshold | 85% of VOUT - provides accurate power-good signaling for system sequencing and fault detection. |
Pinout & Package
IP1202TRPBF uses a thermally enhanced 32-pin QFN package (15.5 mm × 9.25 mm × 2.6 mm, exposed thermal pad) with pin 1 marked by dot. Package meets JEDEC MO-220 standard and requires solder paste stencil optimization for thermal pad reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Primary input power supply | Accepts 5.5–13.2 V; connects to bulk capacitance and must be decoupled locally per channel. |
| PGND | Power ground return | Low-inductance return path for high di/dt switching currents; tied directly to thermal pad. |
| VSW1 / VSW2 | Phase node outputs | Connect to external inductors; each drives one buck phase with complementary 180° timing. |
| FB1 / FB2 | Feedback inputs | Resistor-divider inputs for closed-loop regulation; 0.8 V reference enables precise VOUT setting. |
| SS1 / SS2 | Soft-start control | Capacitor-timed ramp initiation; independent control allows staggered startup of dual outputs. |
| ENABLE | Global enable input | Active-high logic input referenced to VIN; 4.8 V turn-on threshold supports direct 5 V or 12 V control. |
| HICCUP | Overcurrent response mode select | Pulled low for hiccup mode (auto-retry), pulled high for latch-off on overcurrent fault. |
| SYNC | External clock synchronization | Accepts 480–800 kHz square wave; enables phase alignment with system master clock for EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 2-phase synchronous buck integration | Eliminates 16+ discrete components (MOSFETs, drivers, controller, passives) - reduces layout sensitivity and BOM count. |
| Independent per-channel soft start | Enables controlled ramp-up of multiple voltage rails without cross-coupling or sequencing ICs. |
| 180° interleaved phase operation | Halves input/output ripple current vs. single-phase design - cuts required input capacitance by ~75%. |
| Integrated overvoltage protection (OVP) | Triggers at 1.15×VOUT with 25 µs propagation delay - protects downstream FPGAs, ASICs, and memory from catastrophic overvoltage. |
| Thermally robust construction | 125°C maximum block temperature rating with 140°C shutdown - validated for continuous operation in 90°C case environments. |
Applications
| Server VRM | Telecom POL Converter |

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 |
|---|---|---|---|
| MP2960A from Monolithic Power Systems | Single 30 A output only; no dual independent outputs; fixed 600 kHz fSW; lacks SYNC and HICCUP pins. | Suitable for single-rail high-current apps but cannot replace dual-rail sequencing or EMI-controlled sync in multi-output systems. | Select when only one regulated rail is needed and board space is less constrained than thermal limits. |
| TDA21472 from Texas Instruments | Supports dual outputs but requires external PWM controller; higher external component count; 125°C max TBLK vs. 125°C for IP1202TRPBF. | Offers greater flexibility in loop compensation but increases design time and layout risk for high-density boards. | Prefer when custom loop tuning or non-standard switching frequencies (>400 kHz) are required. |
Compared with MP2960A and TDA21472, IP1202TRPBF uniquely combines dual independent outputs, 180° interleaving, external sync, and hiccup/latch overcurrent modes in a single monolithic package - reducing design cycle time and improving thermal predictability in space-constrained POL applications.

FAQ
What is the recommended minimum output inductance for IP1202TRPBF at 300 kHz and 15 A per channel?
The datasheet specifies 1.0 µH as the nominal inductance for 300 kHz operation with 15 A per channel. Using 1.0 µH yields optimal trade-off between ripple current (≈20% of IOUT), efficiency (>90%), and transient response. Inductor DCR should be ≤2 mΩ to maintain accuracy of current-sense-based OCP.
Can IP1202TRPBF operate with only one output enabled while the other is disabled?
Yes - FB2 can be tied to VREF (0.8 V) and SS2 held low to disable Channel 2, allowing single-output operation at up to 30 A using both phases. The device maintains full protection functions (OVP, OTP, hiccup) on the active channel, and PGOOD reflects only Channel 1 status.
How does the IP1202TRPBF handle current sharing between dual outputs?
Current sharing relies on matched internal current-sense resistors and identical external OCSET resistor values. With ROCSET1 = ROCSET2, the device achieves ±5% current matching across channels at 15 A each, verified over –40°C to 125°C ambient per the datasheet Figure 15 test conditions.
Is the thermal pad of IP1202TRPBF electrically connected to any internal node?
No - the exposed thermal pad is internally connected only to the power ground (PGND) plane. It must be soldered to a solid PGND copper area on the PCB with ≥8 thermal vias (0.3 mm diameter) to ensure proper heat dissipation and meet the 125°C maximum block temperature rating.
