Product details

Overview

AEK-POW-100W4V1 from STMicroelectronics is a compact, digitally controlled dual-buck DC-DC converter evaluation board based on the L5964 automotive-grade monolithic regulator IC. It delivers up to 100 W (5 A at 20 V) across a single buck channel, supports fixed outputs (3.3 V/5 V/9 V/15 V/20 V) and Programmable Power Supply (PPS) mode with 20 mV resolution, and integrates short-circuit, overcurrent, and thermal protection for USB Power Delivery in-vehicle applications.

For engineers reviewing the AEK-POW-100W4V1 datasheet, AEK-POW-100W4V1 pinout, AEK-POW-100W4V1 application, or AEK-POW-100W4V1 equivalent, this board enables rapid validation of USB-PD 3.0 PPS compliance, closed-loop current control integration with AEK-USB-2TYPEC1, and automotive-grade power conversion using SPC5 microcontrollers via AutoDevKit library support.

Technical Context

The AEK-POW-100W4V1 implements two independent synchronous step-down regulators (Buck1/Buck2) plus an integrated LDO, all driven by the L5964 IC. It supports constant-voltage and constant-current operation modes, with current limiting programmable from 50 mA to 5 A in 50 mA steps and output voltage adjustable from 3.3 V to 11 V in 20 mV increments.

Hardware-level USB-PD system integration requires coordination with AEK-USB-2TYPEC1 for CC line signaling, VBUS monitoring, and current sensing - routed via J8 (4×20-pin connector). The board lacks onboard current sense amplification; gain adjustment (R803/R804 swap) and port disablement (R304 removal) on the companion board are mandatory for closed-loop operation.

FAQ

Does AEK-POW-100W4V1 support USB-PD 3.0 PPS mode natively?

Yes - it implements full PPS functionality via the L5964 IC, enabling 20 mV output voltage steps from 3.3 V to 11 V and 50 mA current steps from 0.05 A to 5 A. However, PPS negotiation requires external USB-C controller logic (e.g., on AEK-USB-2TYPEC1) and AutoDevKit software stack running on an SPC5 MCU.

Can AEK-POW-100W4V1 operate standalone without a microcontroller?

No - it lacks onboard USB-PD protocol handling or autonomous voltage/current selection logic. All configuration (EN_0/EN_1, Vx_PWM, I_SENSE routing) must be driven by an external MCU (e.g., SPC58 Chorus) via GPIO and analog interfaces; no default fixed-output boot mode is implemented.

What is the role of the L5964 IC on this board?

The L5964 is a monolithic dual 3.5 A buck regulator with integrated LDO, used here in single-channel high-power configuration (5 A via parallel phase control). Its internal error amplifiers, COMP pins, and OCPSET inputs enable both open-loop (fixed setpoint) and closed-loop (current-sense feedback) regulation when paired with AEK-USB-2TYPEC1.

Is thermal protection active during constant-current mode?

Yes - thermal shutdown remains fully functional in constant-current mode. The L5964 monitors die temperature independently of voltage/current loop operation, triggering immediate shutdown if TJ exceeds 150 °C, preserving reliability during sustained high-power loads like car hair dryers or milk warmers.
