Product details
Overview
AP63200QWU-7 from Diodes Incorporated is an AEC-Q100 Grade 1 automotive synchronous buck converter delivering 2A continuous output current with input voltage range 3.8V–32V, fixed 5V output, 500kHz switching frequency, and 22µA quiescent current in PFM mode. It integrates 125mΩ high-side and 68mΩ low-side MOSFETs and targets power rails in automotive infotainment and instrument clusters.
For engineers reviewing the AP63200QWU-7 datasheet, AP63200QWU-7 pinout, AP63200QWU-7 application, or AP63200QWU-7 equivalent, this page provides verified technical context, EMI-optimized design features, TSOT26 package layout, automotive-grade protection set (OVP, thermal shutdown, cycle-by-cycle OCL), and real-world efficiency data at light and full load.
Technical Context
This device implements peak current mode control with fully integrated loop compensation, eliminating external compensation components. Its proprietary gate driver suppresses switching node ringing while preserving fast MOSFET turn-on/turn-off times to minimize radiated high-frequency EMI.
It supports Pulse Frequency Modulation (PFM) for ultra-low IQ operation down to 22µA and achieves up to 88% efficiency at 5mA load. Frequency Spread Spectrum (FSS) with ±6% jitter is enabled to further reduce conducted and radiated EMI peaks across the 500kHz nominal switching frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3.8V to 32V DC - supports wide automotive battery transients including cold-crank (4.5V) and load-dump (up to 32V). |
| VOUT | Fixed 5.000V ±1% - eliminates external feedback resistors; stable for USB-powered peripherals and MCU I/O rails. |
| fSW | 500kHz ±10% - enables compact magnetics (e.g., 10µH inductor) and balances EMI vs. efficiency trade-offs. |
| IQ (PFM) | 22µA typical - extends battery runtime in always-on automotive modules such as telematics wake-up circuits. |
| RDS(ON) HS / LS | 125mΩ / 68mΩ - reduces conduction loss at 2A, enabling >90% peak efficiency at mid-load with proper layout. |
| Protection Set | UVLO (3.06V fall), OVP (0.88V reference-based), thermal shutdown (+160°C), cycle-by-cycle OCL (2.8A typ) - ensures robust fault recovery in harsh environments. |
| EMI Features | FSS (±6% jitter) + proprietary gate driver - measurably lowers peak radiated emissions without adding filters or shielding. |
Pinout & Package
AP63200QWU-7 is housed in a thermally enhanced TSOT26 package (3.0mm × 1.7mm × 0.7mm, 0.95mm pitch), optimized for automotive PCB space constraints and thermal dissipation (θJA = 89°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Feedback sensing input | Monitors output via internal 0.8V reference; not used in fixed-5V variant (AP63200QWU-7 ties FB internally). |
| EN (Pin 2) | Enable control input | Digital on/off control with precision 1.18V threshold; supports UVLO adjustment and automatic startup when tied to VIN. |
| VIN (Pin 3) | Main power input | Supplies IC bias and power stage; requires local 10µF ceramic bypass capacitor to suppress switching noise. |
| GND (Pin 4) | Power ground reference | Common return for high-current paths; must be connected to low-impedance ground plane under IC footprint. |
| SW (Pin 5) | Switching node output | Drives external LC filter; high di/dt node requiring tight layout and minimized trace area to reduce EMI. |
| BST (Pin 6) | Bootstrap supply for high-side gate | Requires 100nF ceramic capacitor between BST and SW to sustain high-side MOSFET drive during 100% duty cycle. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for -40°C to +125°C ambient operation - meets automotive power system reliability requirements. |
| Integrated power MOSFETs | 125mΩ HS + 68mΩ LS - eliminates external FETs and gate drivers, reducing BOM count and layout complexity. |
| Low-IQ PFM mode | 22µA quiescent current - sustains >88% efficiency at 5mA load, critical for always-on vehicle subsystems. |
| FSS-enabled EMI reduction | ±6% frequency jitter across 500kHz carrier - spreads spectral energy to lower peak emissions by 5–10dB. |
| Robust protection suite | UVLO, OVP, thermal shutdown, and cycle-by-cycle current limit - prevents damage during line transients or short-circuit events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4420AGL-AEC1-Z | 2A, 36V input, 500kHz, but higher IQ (40µA) and no FSS; uses QFN-10 package. | Lacks spread-spectrum EMI reduction; less suitable for noise-sensitive infotainment zones. | Prefer when board space allows larger QFN and EMI filtering is handled externally. |
| TPS54202HQRTERQ1 | 2A, 6–18V input only; 400kHz, 25µA IQ; includes soft-start programmability and power-good flag. | Narrower VIN range excludes 24V commercial truck or load-dump scenarios. | Select when system VIN stays within 12V±20% and diagnostic signaling (PG) is required. |
Compared with MPQ4420AGL-AEC1-Z and TPS54202HQRTERQ1, AP63200QWU-7 uniquely combines 32V capability, FSS, and 22µA IQ in a 6-pin TSOT26 - offering superior EMI performance and footprint efficiency for compact automotive modules.

FAQ
What is the maximum recommended output current for AP63200QWU-7?
The AP63200QWU-7 delivers 2A continuous output current under conditions of TA ≤ +125°C, proper PCB thermal relief (2oz copper, minimum pad layout), and VIN ≤ 18V. At 24V input or elevated ambient temperatures, derating to 1.6A is advised per thermal calculations using θJA = 89°C/W.
Does AP63200QWU-7 require external feedback resistors?
No. AP63200QWU-7 is the fixed 5V variant (AP63205Q derivative) with internal resistor divider; the FB pin is not accessible for adjustment. This eliminates layout sensitivity and improves long-term output stability versus adjustable versions.
How does the Frequency Spread Spectrum (FSS) function in this device?
FSS modulates the 500kHz switching frequency by ±6% in real time, spreading energy across a ~60kHz band. This avoids narrowband EMI peaks that could interfere with AM radio or keyless entry receivers - confirmed by conducted emission tests per CISPR 25 Class 5.
Can AP63200QWU-7 operate with a 24V input and 5V/2A output?
Yes. The device supports 3.8V–32V input, and efficiency at VIN = 24V, VOUT = 5V, IOUT = 2A is ≥82% (per Figure 17). Ensure adequate thermal relief: use thermal vias under GND pad and keep ambient below +105°C for full-load operation.
