DER-381 lets designers evaluate ChiPhy AC-DC wall-charger
interface IC
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power
Integrations (Nasdaq: POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today introduced the first reference design for a
Qualcomm® Quick Charge 2.0-enabled charger power supply. Launched
earlier this year, the Quick Charge 2.0 protocol from Qualcomm
(Nasdaq:QCOM) enables users to charge mobile devices, such as tablets
and cellphone handsets, up to 75% faster than when using conventional
USB charging technology.
Power
Integrations has developed the ChiPhy™
family of AC-DC wall-charger interface ICs which, when combined with the
company’s AC-DC switcher ICs, incorporates all of the necessary elements
to add rapid charging functionality to AC-DC wall chargers. The CHY100
IC detects commands from a Quick Charge 2.0-enabled device, and adjusts
the output voltage of the AC-DC wall charger to deliver increased power
to the device’s battery through a standard USB cable. When plugged into
a five-volt USB-powered device without Quick Charge 2.0 capability, CHY100
IC automatically disables the higher-voltage capability to ensure safe
operation and backwards compatibility with older hardware.
An evaluation platform for ChiPhy
ICs, DER-381
describes a CV/CC charger power supply capable of up to 24 W utilizing TOPSwitch™-JX
switcher and CHY100D
interface ICs. The PSU operates from universal input and provides
selectable output voltages (5 V, 9 V, and 12 V) with a maximum constant
current of 2 A. The TOPSwitch-JX
IC maintains virtually constant efficiency across a very wide range of
output voltages and current load conditions.
Comments
Peter Vaughan
, director of application engineering at Power
Integrations: “DER-381
shows, for the first time, how a Quick Charge 2.0 charger power supply
can be successfully implemented using the latest generation of Power
Integrations’ switcher and interface ICs and simple optocoupler
feedback.”
