Diodes Incorporated AP64060QWU-EVM

Overview

AP64060QWU-EVM from Diodes Incorporated is an evaluation module for the AP64060Q 4.5V–40V input, 600mA synchronous buck converter with integrated 600mΩ high-side and 300mΩ low-side MOSFETs, 2.2MHz fixed-frequency operation, <0.1% output ripple at 12V, and proprietary EMI-reduction gate driver. It supports automotive-grade applications including 12V/24V distributed bus supplies and FPGA point-of-load regulation.

For engineers reviewing the AP64060QWU-EVM datasheet, AP64060QWU-EVM pinout, AP64060QWU-EVM application, or AP64060QWU-EVM equivalent, this module enables rapid validation of the AP64060Q's EMI-optimized switching performance, PFM/PWM mode transition behavior, thermal shutdown response, and UVLO programmability under real load transients and input voltage variation.

Technical Context

The AP64060QWU-EVM implements the full reference design per DS44124 Rev. 3–2, featuring a TSOT26-mounted AP64060Q IC, 10µH inductor (L1), 2×10µF ceramic output capacitors (COUT), 2.2µF input capacitor (CIN), 115kΩ/22.1kΩ feedback divider (R1/R2), and 100nF BST capacitor (C5). It supports adjustable output voltages from 0.8V to 26V via FB resistor network.

It demonstrates peak current mode control with internal slope compensation, 1ms soft-start, cycle-by-cycle OCP (0.8–1.3A HS peak limit), 170°C thermal shutdown with 35°C hysteresis, and precision enable threshold (1.21V) for UVLO programming. The board includes test points for VIN, VOUT, SW, EN, FB, and GND to facilitate oscilloscope-based EMI and transient analysis.

FAQ

What is the primary function of the AP64060QWU-EVM?

The AP64060QWU-EVM is a fully assembled evaluation board that demonstrates the electrical performance, protection features, and layout best practices of the AP64060Q synchronous buck converter. It enables engineers to validate efficiency, transient response, EMI behavior, and startup/shutdown sequencing without designing a custom PCB.

Does the AP64060QWU-EVM support adjustable output voltage?

Yes - the board implements the AP64060Q's adjustable output architecture via external resistive feedback (R1/R2). Default configuration sets 5V output using 115kΩ/22.1kΩ; users can replace R1 to achieve other voltages from 0.8V to 26V per Equation 4 in DS44124.

Can the AP64060QWU-EVM be used for automotive qualification testing?

Yes - it hosts the AEC-Q100 Grade 1 qualified AP64060Q (–40°C to +125°C TA), includes IATF 16949-manufactured components, and replicates the thermal pad layout and EMI-optimized routing specified in Diodes' automotive design guidelines.

Is the AP64060QWU-EVM compatible with standard lab equipment?

Yes - it provides accessible test points for VIN, VOUT, SW, EN, FB, and GND, plus screw-terminal input/output connections. All critical nodes are routed to 0.1"-spaced headers compatible with oscilloscope probes, DC power supplies, and electronic loads.
