Power conversion chip saves on charger standby
Power Integrations has unveiled a 3W charger reference design that consumes less than 30mW of no-load power.
Such chargers are commonly sold with products such as cellphones, cordless phones, portable audio players, shavers and other personal electronics.
Chargers using LinkSwitch-LP require just 14 components - the lowest component count available for energy-efficient switched-mode chargers.
"Recent energy-efficiency standards practically eliminate the use of linear-transformer-based external power supplies in key markets such as California", noted Doug Bailey, Vice President of Marketing for Power Integrations.
"LinkSwitch-LP is ideal for designers whose mandate is to meet these standards at the lowest possible cost.
"Chargers using LinkSwitch-LP are vastly simpler than discrete designs, which typically contain dozens of components", Bailey continued.
"LinkSwitch-LP also offers integrated energy-efficiency and safety features that are either unavailable in discrete designs or, at best, require additional components and design effort".
LinkSwitch-LP features a 700V power MOSFET integrated with control and fault protection circuitry on a single silicon chip.
The ICs operate across the universal input range of 85 to 265V AC and achieve an extremely low no-load power consumption of less than 150mW at 265V AC.
The simple on/off control scheme of LinkSwitch-LP provides constant efficiency even at light loads, enabling easy compliance with recent efficiency standards.
LinkSwitch LP is available in lead-free, plastic through-hole DIP8 and surface-mountable SMD8 packages.
Pricing in 1000-piece quantities for the LNK562PN, a 1.9W part in a DIP8 package, is $0.45 each.
The LNK564PN, a 3W part, is priced at $0.49 each.
Small quantities of each type are available from factory stock, with production quantities available 4 weeks ARO. Request a free brochure from Power Integrations ...
