Product details

Overview

TDA21201P7 from Infineon is an integrated synchronous buck power stage combining a MOSFET driver, high-side and low-side Power MOSFETs, and internal bootstrap circuitry in a single TO-220-7-3 package. It delivers up to 30 A DC output current for 12 V input to sub-3.3 V conversion, features 4.8 mΩ low-side and 13.3 mΩ high-side R_DS(on) at T_j = 25 °C, and supports standard 5 V TTL PWM control for motherboard VRMs.

For engineers reviewing the TDA21201P7 datasheet, TDA21201P7 pinout, TDA21201P7 application, or TDA21201P7 equivalent, key selection criteria include its integrated bootstrap capability, thermal resistance (R_thJC = 1.9 K/W), shutdown window (1.2–1.6 V), over-temperature protection at 150 °C, and compatibility with multi-phase PWM controllers without external gate drive components.

Technical Context

The TDA21201P7 implements a fully self-contained synchronous buck power stage with monolithic integration of driver logic, high-side and low-side MOSFETs, and internal charge pump for high-side gate drive-eliminating external bootstrap diodes and capacitors. Its three-state input enables precise shut-down control via a 1.2–1.6 V window lasting >1.5 µs.

It operates across 9–15 V V_CC, exhibits smooth functional ramp-up without abrupt UVLO thresholds, and provides dual V_CC pins with ∆V_CC monitoring (≥0.45 V for >2 µs triggers disable). Thermal coupling between driver and MOSFETs enables unified over-temperature shutdown at ~150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Output Current	30 A DC at V_CC = 12 V, V_OUT ≤ 3.3 V - defines maximum phase current in multi-phase VRMs
R_DS(on) Low-Side	4.8 mΩ @ T_j = 25 °C - minimizes conduction loss in low-side switch during continuous conduction mode
R_DS(on) High-Side	13.3 mΩ @ T_j = 25 °C - balances switching speed and on-resistance for 12 V → 1.x V conversion
IN-to-OUT Delay (ON)	110–150 ns - ensures tight timing alignment with PWM controller for stable multi-phase interleaving
Thermal Resistance (Junction-to-Case)	1.9 K/W - enables direct heatsink mounting on TO-220 tab for high-power density board layouts
Shutdown Input Window	1.2–1.6 V for >1.5 µs - provides noise-immune, low-power disable mode without requiring auxiliary logic
V_CC Operating Range	9–15 V - supports ATX supply tolerances and eliminates need for dedicated bias rail

Use Scenario: Compact, cost-sensitive 4-phase VRM on consumer-grade ATX motherboards powering Intel Core or AMD Ryzen processors.

IC Role / Device Role / Timing Role: Integrated buck stage accepting standard PWM1–PWM4 signals; V_OUT tab directly connects to output inductor and thermal pad.

Use Value: Enables 12 V → 1.2 V conversion at >90% efficiency per phase while fitting within tight board area constraints near CPU socket.

GPU Power Delivery Systems

AI Accelerator Board VRMs

Use Scenario: High-transient response power stage for discrete graphics cards with rapid load changes during gaming or compute workloads.

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated synchronous buck power stage applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR35201	40 V max V_OUT, 40 A rating, QFN-40 package; requires external bootstrap capacitor	Targeted at higher-output-voltage server VRMs (up to 3.3 V); lacks integrated bootstrap	Choose when higher current headroom or QFN thermal performance is required, and board space allows external bootstrap components
MP86957	30 V max V_OUT, 35 A rating, QFN-34 package; includes internal current sense amplifier	Designed for compact client VRMs with integrated current monitoring; no over-temperature shutdown flag output	Prefer when real-time phase current feedback is needed and system-level thermal monitoring replaces integrated shutdown signaling

Compared with IR35201 and MP86957, the TDA21201P7 uniquely combines true bootstrap integration, TO-220 mechanical robustness, and unified thermal shutdown - making it optimal for cost-sensitive, high-reliability motherboard VRMs where layout simplicity and solder-joint integrity are critical.

FAQ

What is the function of the dual V_CC pins (pins 6 and 7)?

Pins 6 and 7 are paralleled V_CC inputs supplying power to the internal gate driver and logic circuits. Their duplication reduces effective trace inductance and improves current sharing, while enabling ∆V_CC monitoring: if voltage difference exceeds 0.45 V for >2 µs, the device disables to prevent malfunction from poor solder joints or asymmetric routing.

Does the TDA21201P7 require external bootstrap components?

No. The TDA21201P7 integrates all bootstrap circuitry-including charge pump and level-shifting logic-within the package. Only GND (pins 1–3), V_CC (pins 6–7), IN (pin 5), and V_OUT (pin 4/tab) connections are required for full operation, eliminating external diodes and capacitors.

How does the shutdown mode operate, and what triggers it?

Applying 1.2–1.6 V to the IN pin for longer than 1.5 µs places the device in shutdown mode, turning off both high-side and low-side MOSFETs. This reduces gate charge losses during no-load conditions. Shutdown ends automatically when IN transitions to <0.8 V (low-side enable) or >2.1 V (high-side enable).

Can the TDA21201P7 be used in non-synchronous buck topologies?

No. The TDA21201P7 is designed exclusively for synchronous buck operation, with complementary high-side and low-side MOSFETs controlled by a single PWM input. It lacks diode emulation or forced discontinuous conduction mode (DCM) support, and its internal architecture assumes continuous synchronous switching.
