Product details
Overview
AP61202Z6-7 from Diodes Incorporated is a 2A synchronous buck converter with 2.3V–5.5V input, integrated 110mΩ high-side and 80mΩ low-side MOSFETs, 1.3MHz switching frequency (at VIN=5V/VOUT=1.8V), 0.6V ±2% reference, and power-good (PG) output. It delivers regulated DC-DC conversion for FPGA/DSP core supplies in compact consumer and industrial edge devices.
For engineers reviewing the AP61202Z6-7 datasheet, AP61202Z6-7 pinout, AP61202Z6-7 application, or AP61202Z6-7 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOT563 pin functions, confirmed alternative parts with functional differences, and supply support for production ramp-up.
Technical Context
The AP61202Z6-7 uses Constant On-Time (COT) control to achieve fast transient response without external compensation, with on-time inversely proportional to VIN and directly proportional to VOUT. Its internal 0.6V reference feeds an error amplifier that drives a one-shot timer controlling Q1 turn-on duration.
It operates in Pulse Frequency Modulation (PFM) mode at light loads-reducing switching frequency to maintain up to 89% efficiency at 5mA-and includes a 0.5ms soft-start, open-drain PG output with 55μs rise delay, and comprehensive protection including UVLO (1.84V falling), VIN OVP (6.3V), peak/valley current limiting, and thermal shutdown at +160°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.3V to 5.5V - supports single-cell Li-ion, USB-powered, and 3.3V/5V distributed bus inputs without pre-regulation. |
| Output Current | 2A continuous - sufficient for FPGA I/O banks or dual-core microcontroller cores with margin. |
| fSW | 1.3MHz typical (VIN=5V, VOUT=1.8V) - enables use of small 1μH inductors and reduces output ripple filtering footprint. |
| IQ (PFM) | 19μA typical - extends battery runtime in always-on sensor nodes or standby subsystems. |
| RDS(ON) HS/LG | 110mΩ / 80mΩ - minimizes conduction loss at 2A, enabling >85% efficiency across 0.5A–2A load range. |
| VFB Accuracy | 0.6V ±2% - ensures ±2% output voltage tolerance over temperature and line/load, critical for logic supply compliance. |
| PG Thresholds | 95% rise / 90% fall of VOUT - provides reliable power sequencing feedback with 5% hysteresis for noise immunity. |
Pinout & Package
AP61202Z6-7 is housed in a thermally enhanced SOT563 package (1.6mm × 1.6mm × 0.55mm, 0.5mm pitch), optimized for high-density PCB layouts and capable of 141°C/W junction-to-ambient thermal resistance on standard 2-layer FR-4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Feedback sensing input | Connects to resistor divider (R1/R2) to set output voltage; 0.6V reference enables VOUT = 0.6V × (1 + R1/R2). |
| GND (Pin 2) | Power ground reference | Primary return path for high-current SW node and IC bias; must be tied to low-impedance ground plane under IC. |
| VIN (Pin 3) | Main power input | Supplies both IC bias and high-side/low-side MOSFETs; requires local 10µF ceramic bypass capacitor to GND. |
| SW (Pin 4) | Switching node output | Drives external inductor; connects to LC filter input; high dv/dt node requiring short, low-inductance layout. |
| EN (Pin 5) | Enable control input | Logic-level digital enable (0.83V low / 0.91V high thresholds); 0.1μA shutdown current enables system-level power gating. |
| PG (Pin 6) | Open-drain power-good indicator | Pulls low during soft-start or if VOUT deviates >5% from target; internal 5MΩ pull-up to VIN; 55μs rise delay prevents false triggers. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Power MOSFETs | 110mΩ HS + 80mΩ LS eliminates external FETs and gate drivers, reducing BOM count and layout complexity. |
| Constant On-Time Control | Enables stable operation without loop compensation components, simplifying design for variable input/output conditions. |
| Power-Good Output | Provides system-level power sequencing confirmation with ±5% regulation window and 55μs glitch immunity. |
| Light-Load PFM Mode | Maintains ≥85% efficiency down to 10mA, extending battery life in intermittent-activity applications like IoT sensors. |
| Comprehensive Protection | UVLO (1.84V), VIN OVP (6.3V), thermal shutdown (+160°C), and valley/peak current limits prevent fault propagation. |
Applications
| FPGA Core Supply | DSP I/O Rail |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2143GJ-Z | 2.5V–5.5V input, 2A, 1.5MHz, no PG output, 25μA IQ (PFM) | Lacks power-good signaling; requires external circuitry for sequencing-critical systems. | Select when PG is unnecessary and higher fSW justifies slightly higher IQ. |
| TI TPS62231DRVR | 2.05V–6V input, 2A, 3MHz, 17μA IQ (PFM), no PG, smaller DSBGA package | No PG output; 3MHz operation demands tighter layout control and higher-cost MLCCs. | Prefer for ultra-compact designs where board area is constrained more than sequencing fidelity. |
Compared with MP2143GJ-Z and TPS62231DRVR, AP61202Z6-7 uniquely integrates PG functionality and maintains lower IQ (19μA) at 1.3MHz, making it optimal for cost-sensitive, sequencing-dependent embedded systems where reliability and ease of validation are prioritized over maximum frequency or minimum package size.

FAQ
What is the function of the PG pin on AP61202Z6-7?
The PG (Power-Good) pin is an open-drain output that pulls low during soft-start and whenever the output voltage falls outside ±5% of its regulated value. It features a 55μs rise delay and internal 5MΩ pull-up to VIN, enabling reliable system power sequencing without external components.
Can AP61202Z6-7 operate with a 2.5V input supply?
Yes. AP61202Z6-7 supports input voltages from 2.3V to 5.5V, making it fully compatible with 2.5V sources. At 2.5V input and 1.2V output, it delivers 2A with >83% efficiency (per Figure 10) and maintains stable COT control due to its adaptive on-time calculation.
How does the AP61202Z6-7 handle thermal overload?
It incorporates thermal shutdown at +160°C junction temperature with +30°C hysteresis. When triggered, both MOSFETs disable and the device remains latched off until junction temperature drops to +130°C, preventing repeated cycling and ensuring safe cooldown before automatic recovery.
Is an external feed-forward capacitor required for AP61202Z6-7?
No. Unlike AP61200/AP61201, AP61202Z6-7 uses PG instead of OUT and does not require a feed-forward capacitor (C3). The PG pin replaces the floating OUT connection, eliminating the need for C3 while adding sequencing capability.
