Product details
Overview
AP62200Z6-7 from Diodes Incorporated is a 2A synchronous buck converter with 4.2V–18V input range, integrated 90mΩ high-side and 65mΩ low-side MOSFETs, 750kHz switching frequency, 135μA quiescent current in PFM mode, and 0.8V ±1% reference voltage - designed for point-of-load regulation in FPGA/DSP power supplies and consumer electronics.
For engineers reviewing the AP62200Z6-7 datasheet, AP62200Z6-7 pinout, AP62200Z6-7 application, or AP62200Z6-7 equivalent, key selection criteria include its COT control architecture for fast transient response, proprietary gate driver for EMI reduction, thermal shutdown at +160°C, and TSOT26 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements Constant On-Time (COT) control to deliver pseudo-fixed-frequency operation across input voltage variations while ensuring rapid load transient recovery and minimal output voltage ripple. Its one-shot on-time computation dynamically adjusts tON based on VIN/VOUT ratio and nominal fSW, enabling stable loop behavior without external compensation.
The proprietary gate driver suppresses switching node ringing by optimizing MOSFET turn-on/turn-off timing without degrading edge speed, directly reducing high-frequency radiated EMI. Protection includes cycle-by-cycle valley current limiting (2.8A typ), UVLO with 3.9V rising threshold, and thermal shutdown with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4.2V to 18V DC - supports wide-input industrial and consumer bus rails including 5V, 12V, and 15V systems. |
| IOUT Max | 2A continuous - sufficient for powering FPGA core logic, DSP I/O banks, or ASIC subsystems. |
| fSW | 750kHz typical at VIN=12V, VOUT=5V - enables compact LC filter design with 4.7μH inductor and 2×22μF output capacitance. |
| IQ (PFM) | 135μA typical - extends battery life in always-on subsystems and low-power standby modes. |
| VFB Ref | 0.800V ±1% at +25°C - sets precise output voltage via external resistor divider; supports 0.8V–7V programmable VOUT. |
| RDS(ON) HS/LS | 90mΩ / 65mΩ - minimizes conduction loss and improves full-load efficiency up to 90% at 1A. |
| tSS | 2.5ms soft-start - prevents output overshoot and limits inrush current during power-up sequencing. |
Pinout & Package
AP62200Z6-7 is packaged in TSOT26 (Standard), a 6-pin, 1.7mm × 2.9mm, 0.95mm height surface-mount package with exposed thermal pad for enhanced thermal dissipation (θJA = 70°C/W on 2-layer FR-4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 3) | Power Input | Supplies IC bias and high-side MOSFET gate drive; requires ≥10μF ceramic bypass capacitor to GND for noise suppression. |
| SW (Pin 2) | Switching Node | Connects to inductor input; carries high di/dt current - layout must minimize loop area to reduce EMI. |
| GND (Pin 1) | Power Ground | Primary return path for high-current switching and IC ground; must be tied to thermal pad and low-impedance plane. |
| BST (Pin 6) | Bootstrap Supply | Drives high-side MOSFET gate; requires 100nF ceramic capacitor between BST and SW for charge replenishment. |
| EN (Pin 5) | Enable Control | Digital input with 1.2V logic-high threshold; floating EN enables auto-start via internal 1.5μA pull-up current source. |
| FB (Pin 4) | Feedback Sense | Monitors resistive divider output; regulates VOUT by comparing against 0.8V internal reference. |
Key Features
| Feature | Design Value |
|---|---|
| Constant On-Time (COT) Control | Enables <10μs load transient recovery and eliminates need for external compensation network. |
| Proprietary Ringing-Free Gate Driver | Reduces high-frequency radiated EMI without increasing MOSFET switching losses or compromising tON/tOFF. |
| Low-IQ PFM Mode | 135μA quiescent current at light load preserves battery runtime in always-on applications like remote controls or IoT sensors. |
| Integrated Protection Suite | Includes undervoltage lockout (UVLO), cycle-by-cycle valley current limit, and thermal shutdown with 20°C hysteresis. |
| Lead-Free & Halogen-Free | Fully RoHS 3 compliant (<900ppm Br/Cl, <1000ppm Sb); qualified for industrial temperature range (−40°C to +125°C). |

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, but higher IQ (260μA) and no PFM mode. | Limited light-load efficiency (<75% @5mA); less suitable for battery-backed standby rails. | Prefer AP62200Z6-7 when >84% light-load efficiency and EMI-sensitive layouts are required. |
| RT7297BGS (Richtek) | Adjustable fSW (300–2000kHz), 0.6V ref, 2A, but lacks proprietary EMI suppression and has 250μA IQ. | Requires external EMI filters in Class B environments; larger solution size due to external compensation. | Choose AP62200Z6-7 for drop-in replacement where board space, thermal performance, and EMI compliance are critical. |
Compared with MP2451DT-LF-Z and RT7297BGS, AP62200Z6-7 delivers superior light-load efficiency via PFM, lower EMI through optimized gate drive, and tighter thermal management with 20°C shutdown hysteresis - making it optimal for compact, thermally constrained, and emission-sensitive designs.

FAQ
What is the recommended input capacitor for AP62200Z6-7?
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 during load transients. For improved ripple rejection and hold-up time, pair it with a 22μF–47μF bulk tantalum or aluminum polymer capacitor.
Can AP62200Z6-7 operate with an output voltage below 0.8V?
No - the internal reference voltage is fixed at 0.800V ±1%, and the FB pin senses the resistive divider output. Setting VOUT below 0.8V would violate regulation accuracy and is outside the specified operating range per datasheet Section 6 (Recommended Operating Conditions).
How does the EN pin behave when left unconnected?
When EN is floating, an internal 1.5μA pull-up current source charges the pin to the 1.2V logic-high threshold, enabling automatic startup after power-up. No external pull-up is needed, though a small capacitor (e.g., 1nF) can be added to delay startup for power-rail sequencing.
Is AP62200Z6-7 qualified for automotive applications?
AP62200Z6-7 itself is not AEC-Q100 qualified; however, Diodes offers automotive-grade variants (e.g., AP62200T) with tighter reference voltage (0.763V) and qualification support. For automotive use, contact Diodes or Aetrix for PPAP-capable, IATF 16949-manufactured alternatives.
