Product details
Overview
TDA21201-P7 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 RDS(on) of 13.3 mΩ (HS) and 4.8 mΩ (LS) at Tj = 25 °C, and supports standard 5 V TTL PWM control signals in multi-phase VRMs on server and motherboard applications.
For engineers reviewing the TDA21201-P7 datasheet, TDA21201-P7 pinout, TDA21201-P7 application, or TDA21201-P7 equivalent, key selection criteria include integrated bootstrap elimination, thermal resistance (RthJC = 1.9 K/W), shutdown mode via 1.2–1.6 V input window, compatibility with 2-/3-/4-/6-phase PWM controllers, and validated operation across 9–15 V VCC.
Technical Context
The TDA21201-P7 implements a fully self-contained synchronous buck power stage with monolithic integration of gate driver logic, high-side and low-side MOSFETs, and internal charge pump for high-side gate drive-eliminating external bootstrap capacitors and diodes. Its three-state input enables precise shut-down control independent of PWM signal polarity.
It operates across 9–15 V VCC with no sharp UVLO threshold; functionality scales smoothly as supply voltage rises, and overtemperature protection triggers at 150 °C to disable both FETs simultaneously. The device uses Infineon's multi-chip assembly technology to achieve low thermal resistance and tight thermal coupling between driver and MOSFET dies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Output Current | 30 A DC at VCC = 12 V, VOUT ≤ 3.3 V - defines maximum per-phase load capability in multi-phase VRMs |
| RDS(on) High-Side | 13.3 mΩ @ Tj = 25 °C - determines conduction loss and thermal rise under 15 A RMS conditions |
| RDS(on) Low-Side | 4.8 mΩ @ Tj = 25 °C - enables high efficiency in low-VOUT domains (e.g., 1.2–1.8 V CPU cores) |
| IN-to-OUT Delay (td(ON)) | 110–150 ns - ensures timing alignment with fast-switching PWM controllers up to 500 kHz |
| Shutdown Input Window | 1.2–1.6 V for >1.5 µs - provides noise-immune, low-power disable mode without external logic |
| Thermal Resistance RthJC | 1.9 K/W - enables direct heatsink mounting on TO-220 tab for high-power density board layouts |
| VCC Range | 9–15 V - supports ATX-compatible 12 V rails with ±25 % tolerance without regulation circuitry |
Pinout & Package
Package: TO-220-7-3 - thermally enhanced through-hole package with exposed metal tab (Pin 4) serving as VOUT and primary heat path; pins 1–3 are internally shorted GND terminals for low-inductance grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Internally bonded ground nodes - reduce common-source inductance and improve shoot-through immunity |
| 4 / Tab | VOUT | Common drain node of HS/LS MOSFETs and thermal interface - connects directly to output inductor and PCB copper pour |
| 5 | IN | Three-state TTL-compatible input - accepts 0.4 V (Low), 4.5 V (High), or 1.4 V (shutdown) PWM signals |
| 6, 7 | VCC | Dual-supply pins for 12 V gate drive - paralleled internally to lower impedance and support ∆VCC fault detection |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Bootstrap Circuitry | Eliminates external capacitor/diode - reduces BOM count by ≥3 components and layout area by ~25 mm² per phase |
| Thermally Coupled Overtemperature Protection | Single 150 °C trip point disables both MOSFETs and driver - prevents localized hot-spot failure in high-current transients |
| Dual VCC Pins with ∆VCC Monitoring | Detects >0.45 V mismatch for >2 µs - flags solder joint defects or trace opens before catastrophic failure |
| Three-State Input Interface | Shut-down mode draws only 10–22 mA ICC - cuts gate-charge losses during idle, improving light-load efficiency |
| Optimized MOSFET Pairing | HS RDS(on) = 13.3 mΩ, LS RDS(on) = 4.8 mΩ @ 25 °C - balances conduction loss distribution for 12 V → 1.2–3.3 V conversion |

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 VIN, 60 A peak, QFN-40 package, requires external bootstrap capacitor | Targeted at higher-current, higher-frequency (>1 MHz) digital multiphase controllers with PMBus interface | Select when digital telemetry, programmable slew rate, or >40 A per phase is required |
| MP86957 | 30 V max VIN, 40 A peak, QFN-34 package, integrated current sense amplifier, no shutdown pin | Optimized for space-constrained client VRMs with analog PWM inputs and no multi-phase coordination | Select when board area is critical and current sensing must be integrated without external resistors |
Compared with IR35201 and MP86957, the TDA21201-P7 offers superior thermal performance (RthJC = 1.9 K/W vs. ≥3.5 K/W), eliminates external bootstrap components, and provides deterministic shutdown control - making it optimal for cost-sensitive, thermally demanding 12 V input VRMs where analog PWM compatibility and reliability are prioritized over digital configurability.

FAQ
What is the maximum recommended switching frequency for TDA21201-P7?
The TDA21201-P7 is characterized and validated for operation up to 500 kHz, with typical timing parameters (td(ON) = 110–150 ns, tr = 10–25 ns) supporting clean edge transitions. Operation beyond 500 kHz increases switching losses disproportionately due to fixed gate-drive strength and internal parasitic capacitances, and is not guaranteed across temperature or process variation.
Does TDA21201-P7 require external bootstrap components?
No. The TDA21201-P7 integrates a complete bootstrap charge pump and level-shifting circuitry for the high-side MOSFET gate drive. Only VCC (12 V), GND, IN (PWM), and VOUT connections are required - no external capacitor, diode, or resistor is needed for bootstrap functionality.
How does the shutdown mode function electrically?
Applying 1.2–1.6 V to the IN pin for >1.5 µs places the device in shutdown: both MOSFETs turn off, gate drivers enter high-impedance state, and quiescent current drops to 10–22 mA. The mode exits automatically when IN transitions to <0.8 V (Low) or >2.1 V (High), restoring normal PWM-controlled operation without reset or delay.
Can TDA21201-P7 be used in non-synchronous buck topologies?
No. The TDA21201-P7 is strictly a synchronous buck stage with complementary high-side and low-side MOSFETs. It lacks diode emulation or freewheeling diode control logic. Using it in non-synchronous configurations risks shoot-through, uncontrolled body-diode conduction, and thermal runaway - the device is not rated or characterized for such operation.
