Product details
Overview
AP63200WU-7 from Diodes Incorporated is a 2A synchronous buck DC/DC converter with 3.8V–32V input range, integrated 125mΩ high-side and 68mΩ low-side MOSFETs, 500kHz fixed-frequency PWM operation, 0.8V ±1% reference, and 22µA quiescent current. It delivers regulated step-down power in space-constrained industrial and consumer systems requiring EMI-compliant, low-noise 5V or adjustable outputs.
For engineers reviewing the AP63200WU-7 datasheet, AP63200WU-7 pinout, AP63200WU-7 application, or AP63200WU-7 equivalent, this device supports critical design tasks including input voltage UVLO programming via EN pin, FSS-enabled EMI reduction, PFM/PWM mode selection, and thermal-safe 2A load delivery in TSOT26 packaging.
Technical Context
The AP63200WU-7 implements peak current mode control with internal slope compensation and a 4ms soft-start timer to prevent output overshoot. Its oscillator operates at a fixed 500kHz frequency with ±6% Frequency Spread Spectrum (FSS) to disperse switching noise across a wider band.
It integrates a proprietary multi-level gate driver that suppresses SW node ringing without degrading rise/fall times, and features cycle-by-cycle overcurrent protection with hiccup-mode recovery. The EN pin provides precision 1.18V enable threshold and supports external UVLO programming via resistive divider.

Pinout & Package
AP63200WU-7 is housed in a thermally enhanced, lead-free TSOT26 package (2.9mm × 1.6mm × 0.6mm), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 FB | Feedback sensing input | Connects to resistor divider to regulate output; internal 0.8V reference sets VOUT = 0.8V × (1 + R1/R2) |
| 2 EN | Enable control input | Digital ON/OFF control with 1.18V rising threshold; supports UVLO programming and startup sequencing |
| 3 VIN | Main power input | Accepts 3.8–32V; requires local 10µF ceramic bypass capacitor to suppress switching transients |
| 4 GND | Power ground reference | Common return path for VIN, SW, BST, and FB; must connect to low-impedance ground plane |
| 5 SW | Switching node output | Drives external inductor; exhibits minimized ringing due to proprietary gate driver; connects to BST via 100nF capacitor |
| 6 BST | Bootstrap supply for high-side MOSFET | Requires 100nF capacitor between BST and SW to sustain gate drive voltage during high-side conduction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power Stage | 125mΩ HS + 68mΩ LS MOSFETs - eliminates external switch losses and reduces BOM count by 4 components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2451DT-LF-Z (Monolithic Power) | 550kHz fixed freq, 0.8V ref, 2.2A rating, no FSS, higher IQ (65µA) | Lacks integrated EMI reduction features; requires external snubber for CISPR compliance | Choose when cost sensitivity outweighs EMI certification requirements and board area allows larger filter |
| TPS54202HDDCR (TI) | 600kHz, 2A, 25µA IQ, integrated soft-start, but no FSS or ringing suppression | Higher EMI baseline necessitates additional ferrite beads and shielded inductors | Select for TI ecosystem compatibility and enhanced current-sense accuracy, not EMI-critical designs |

FAQ
What is the maximum allowable input voltage for AP63200WU-7?
The AP63200WU-7 supports a continuous input voltage range of 3.8V to 32V. Its absolute maximum rating is +35.0V DC (or +40.0V for ≤400ms transient), verified per Diodes DS41326 Rev. 3–2 Absolute Maximum Ratings table. Exceeding 32V during normal operation risks violating recommended conditions and may trigger UVLO shutdown below 3.3V rising threshold.
Does AP63200WU-7 support adjustable output voltage?
No - AP63200WU-7 is the fixed 5.0V output variant (as indicated by suffix '-7' and confirmed in datasheet Section 1: "Fixed Output Voltage o 5.0V: AP63205"). Unlike AP63200/AP63201, it lacks external feedback divider capability and internally configures VOUT = 5.00V ±1% (4.95–5.05V) at CCM.
How does the EN pin function for power sequencing?
The EN pin provides precise 1.18V (typical) enable threshold with 440mV hysteresis. When pulled above 1.18V, it initiates 4ms soft-start; below 1.10V, it shuts down with 1µA ISHDN. An internal 1.5µA pull-up allows direct VIN connection for automatic startup, while a 4µA hysteresis current source enables external UVLO programming using two resistors per datasheet Figure 22.
What thermal derating applies to AP63200WU-7 at 70°C ambient?
With θJA = 89°C/W (TSOT26 on 2oz FR-4), a 70°C ambient yields ~27°C rise at 1W dissipation, keeping TJ well below +125°C limit. Per datasheet Figure 24, full 2A output is supported up to +75°C ambient; at +70°C, no derating is required if PCB copper area matches minimum pad layout (120mm² exposed GND).
