Fairchild Semiconductor International (South Portland, ME) announced that Dong Yang Instrument (Korea), a manufacturer of power supply instruments and systems for electronic products, has specified Fairchild's FSDH0165D, Fairchild Power Switch (FPS), to power its TAD137 mobile phone charger used in Samsung cellular phone applications.
The FSDH0165D power switch is a voltage-mode, pulse-width modulated controller and SenseFET (LDMOS) power switch element integrated into a single chip that consumes just 0.3W, compared to 0.5W for typical alternatives.
Dong Yang Instrument has chosen the FSDH0165D for its low power consumption and space-saving efficiencies, which are achieved through the use of a 650V BCDMOS process. The resulting advantages are designs using fewer external components as well as a reduction in PC board space requirements. Dong Yang Instrument chose the FSDH0165D to meet the high-quality standards required by Samsung's mobile phone chargers.
