Highly integrated devices enable charger designs up to 10 W with only
28 components
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power
Integrations (Nasdaq:POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today announced the launch of its LinkSwitch™-3
family of highly integrated monolithic switching ICs. The new devices
deliver accurate primary-side regulation for chargers and adapters up to
10 W, making them suitable for smartphones, tablets and other mobile
devices, particularly those subject to 30 mW no-load limitations, such
as upcoming mandatory US DoE EPS efficiency regulations and EU CoC Tier
2 guidelines.
LinkSwitch-3
ICs simplify CV/CC charger designs by eliminating the need for
opto-couplers and secondary-side control circuitry; a 10 W charger, for
example, can be implemented using only 28 external components. The new
devices provide highly accurate output voltage and current regulation,
compensating for transformer and internal parameter tolerances along
voltage variation from the AC line. LinkSwitch-3
ICs incorporate a 725 V power MOSFET, on/off-control state machine,
high-voltage switched current source for self-biasing, frequency
jittering to minimize EMI, plus cycle-by-cycle current limit and
hysteretic thermal shutdown circuitry. The ICs also feature selectable
cable drop compensation for improved voltage tolerance over load.
Comments
Silvestro Fimiani
, senior product marketing manager for Power
Integrations: “The smart mobile device market is highly dynamic; LinkSwitch-3
ICs meet all of the most challenging new requirements. In addition to 10
W maximum output power, the new devices meet the anticipated US DoE
efficiency regulations, the EU’s CoC 2016 Tier 2 guidelines, China’s USB
charger specification and market demand for 30 mW no-load performance
with fast transient response.”
LinkSwitch-3
switcher ICs are sampling now in SO-8,
eSIP-7 and eSOP-12 packages. The product datasheet is available on
the Power
Integrations website at http://www.powerint.com/en/products/linkswitch-family/linkswitch-3.
