earns USB-IF
certification for complete
USB PD EPR solution;
efficiently delivers up to
140W from a single adapter
Geneva, Switzerland,
February 28,
2023 –
STMicroelectronics (NYSE: STM), a global semiconductor
leader serving customers across the spectrum of electronics
applications, has achieved USB-IF (USB Implementers Forum)
certification of two ICs for use in adapter (source) and device
(sink) sides of a USB Power Delivery (USB PD) EPR1 power
supply/charger product. The new ICs extend the range of a universal
charger to 140W. Now, a single AC to DC adapter can charge
equipment such as computers, smart-home actuators, power tools, and
e-bikes, as well as traditional applications including smartphones,
tablets, and smartwatches.
“Leading the way among semiconductor manufacturers, ST is now
able to deliver USB-IF-certified reference designs and chips to
meet customers’ demands for a high-power, industry-standard
universal charger/adapter,” said Matteo Lo Presti, Executive Vice
President Analog Sub-Group, Analog, MEMS and Sensors Group,
STMicroelectronics. “By moving quickly to support USB PD EPR and
achieve certification, we are accelerating the replacement of
custom power plugs and DC barrels in numerous applications with a
USB-C® connector. This allows charging with a universal AC or DC
adapter, reducing cost and environmental impact.”
Certified by the USB-IF to deliver up to 140W (28V@5A), the
REF_STUSB140W (sink) and the ST-ONEHP (source) represent two halves
of the complete USB PD reference design for the solution. The sink
reference design assures designers of an efficient, cost-effective
working solution for seamless USB PD integration. The ST-ONEHP is
supplied pre-loaded with certified USB PD 3.1 EPR firmware.
Together, the new USB solutions enable a larger universe of
applications to adopt a USB-C connector and hence allow charging
from a universal AC to DC adapter. This reduces the number of
adapters the end user needs to carry and cuts e-waste, while also
lowering transportation costs and CO2 emissions.
“The USB PD 3.1 specification represents a significant
breakthrough to satisfy the charging demands of a wider range of
applications beyond 100W,” said Jeff Ravencraft, USB-IF President
and COO. “As one of the first USB PD EPR reference designs to
achieve USB-IF Certification, ST’s latest ICs will accelerate the
industry’s transition from proprietary power connectors to USB
Type-C®.”
An active contributor to the USB PD 3.1 specification which
includes the Extended Power Range (EPR) definition, the ST
solutions are among the first designs certified.
Further Technical Information
ST’s application (sink) side reference design is based on an
STM32, an STUSB1602 analog front-end IC, high-voltage protection
devices, and a dedicated software stack. The design supports
protocol fine tuning and addresses a large range of
applications.
The adapter (source) side design delivers up to 140W (28V@5A)
output from an ST-ONEHP digital controller specifically designed
for USB PD 3.1 EPR chargers. The controller integrates an Arm®
Cortex® M0+ core, an offline programmable controller with
synchronous rectification, and a USB PD PHY in a single package. It
pairs with ST’s MasterGaN1 power stage to create the world’s
highest power density chargers for any battery powered device,
appliance or smart mobility application, exceeding 25W/in.3 with
140W output power and 94% peak efficiency.
Samples of the ST-ONEHP are already available in a SSOP36 leaded
package, priced from $3.90 for orders of 1000 pieces.
Evaluation boards of the SINK and SOURCE solutions will be
available on request in Q2’2023.
