Product details
Overview
AP62200TWU-7 from Diodes Incorporated is a 2A synchronous buck DC-DC converter with 4.2V–18V input range, integrated 90mΩ high-side and 65mΩ low-side MOSFETs, 750kHz fixed switching frequency, 0.763V ±1% reference voltage, and proprietary EMI-optimized gate driver. It delivers regulated 5V/3.3V point-of-load power in flat-panel TVs, gaming consoles, and FPGA supplies.
For engineers reviewing the AP62200TWU-7 datasheet, AP62200TWU-7 pinout, AP62200TWU-7 application, or AP62200TWU-7 equivalent, key selection criteria include its 135μA PFM quiescent current, COT control for fast transient response, TSOT26 package thermal resistance (θJA = 70°C/W), and EN pin programmable UVLO threshold (1.2V).
Technical Context
The AP62200TWU-7 employs Constant On-Time (COT) control with input-voltage–compensated on-time calculation (tON = VOUT / (VIN × fSW)), enabling pseudo-fixed-frequency operation across 4.2V–18V input while maintaining fast load transient response and stable loop behavior without external compensation.
Its proprietary gate driver suppresses switching-node ringing without extending MOSFET turn-on/turn-off times, directly reducing high-frequency radiated EMI. The device operates in PFM at light loads (≤5mA) to achieve 84% efficiency and transitions seamlessly to CCM above the critical conduction boundary defined by (VIN−VOUT)·tON/(2L).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4.2V to 18V DC - supports 5V/12V distributed bus inputs without pre-regulation |
| IOUT Max | 2A continuous - sufficient for FPGA core, DSP, or ASIC I/O rail power delivery |
| VREF | 0.763V ±1% at +25°C - sets output via resistor divider; enables precise 3.3V/5V generation |
| fSW | 750kHz typical - balances EMI, inductor size, and efficiency in compact designs |
| IQ (PFM) | 135μA typical - minimizes standby power loss in always-on consumer electronics |
| RDS(ON) HS/LS | 90mΩ / 65mΩ - reduces conduction loss and thermal stress at full 2A load |
| tSS | 2.5ms soft-start - prevents output overshoot and inrush current during power-up |
Pinout & Package
AP62200TWU-7 is packaged in TSOT26 (Standard), a 6-pin, 1.7mm × 2.9mm, 0.95mm height surface-mount package with exposed thermal pad for enhanced heat dissipation (θJA = 70°C/W on 2-layer FR-4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 3) | Power Input | Accepts 4.2V–18V supply; requires local 10μF ceramic bypass capacitor to GND |
| SW (Pin 2) | Switching Node | Connects to inductor; carries high di/dt; layout critical for EMI control |
| GND (Pin 1) | Power Ground | Primary return path for high-current loops; must be low-inductance connection |
| BST (Pin 6) | Bootstrap Supply | Drives high-side MOSFET gate; requires 100nF ceramic capacitor between BST and SW |
| EN (Pin 5) | Enable Control | Logic-level input (1.2V threshold); floating enables auto-start; supports power sequencing |
| FB (Pin 4) | Feedback Sense | Monitors output voltage via resistive divider; regulates VOUT to 0.763V reference |
Key Features
| Feature | Design Value |
|---|---|
| EMI-optimized gate driver | Eliminates switching-node ringing without sacrificing MOSFET switching speed, reducing radiated noise compliance risk |
| Cycle-by-cycle valley current limit | 2.8A typical current limit protects against short-circuit and overload without external sensing components |
| Thermal shutdown with hysteresis | Triggers at +160°C with +20°C hysteresis, enabling safe recovery after overtemperature events |
| Undervoltage lockout (UVLO) | 3.6V falling threshold prevents erratic startup during brown-out conditions |
| Lead-free & RoHS 3 compliant | Fully halogen- and antimony-free "Green" construction meeting EU Directive 2015/863/EU |

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) | Fixed 2.2MHz fSW, 0.8V ref, 2A rating, no BST capacitor required | Better suited for space-constrained designs needing higher fSW and smaller inductors | Select when board area is critical and 2.2MHz switching is acceptable for EMI filtering |
| TPS562211 (Texas Instruments) | Adaptive COT, 0.6V ref, 2A, integrated boot diode, 500kHz–1.7MHz adjustable fSW | Offers programmable frequency and lower VREF for sub-1V core rails | Choose when designing for multi-rail systems requiring frequency synchronization or <1V outputs |
Compared with MP2451DT-LF-Z and TPS562211, AP62200TWU-7 provides superior EMI performance via its proprietary ringing-free gate driver and lower PFM IQ (135μA vs. ≥200μA), making it optimal for noise-sensitive consumer audio/video applications where thermal and standby power constraints coexist.

FAQ
What is the recommended input capacitor for AP62200TWU-7?
A minimum 10μF X5R/X7R ceramic capacitor placed close to VIN and GND pins is required to suppress high-frequency switching noise and stabilize input voltage. For improved ripple suppression and hold-up time, pair it with a 22μF bulk capacitor. Layout must minimize loop area between VIN, GND, and SW pins to reduce EMI.
Can AP62200TWU-7 operate with an output voltage below 0.8V?
No. The internal reference voltage is fixed at 0.763V ±1%, and the feedback network must be configured to scale VOUT such that the FB pin voltage equals this reference. Output voltages below 0.763V are not supported; the lowest achievable VOUT is 0.763V (with direct FB-to-VOUT connection), and practical minimums start at ~0.8V due to resistor tolerance and divider error.
How does the EN pin affect UVLO behavior?
The EN pin doubles as a UVLO programming input: applying a resistive divider from VIN to EN sets custom rising/falling thresholds. With internal 1.5μA pull-up, EN floats to ~1.2V at startup, enabling automatic operation. External resistor networks allow precise brown-out detection (e.g., 3.6V falling threshold) without additional components.
Is AP62200TWU-7 qualified for automotive applications?
AP62200TWU-7 itself is not AEC-Q100 qualified; however, Diodes offers automotive-grade variants (e.g., AP62200WU-7) with PPAP capability, IATF 16949 manufacturing, and extended temperature validation.
