Fairchild Semiconductor Launches the FSDH0165 Power Switch

Fairchild Semiconductor (New York, NY) introduced a single-chip power switch, the FSDH0165, which is suitable for use in adapter/chargers for mobile phones and low-power switch-mode power-supply applications. The FSDH0165 is a voltage-mode PWM controller and LDMOS SenseFET power-switching element. It is integrated into a single chip and packaged in an 8-lead DIPH.

The FSDH0165 consumes 0.3W. It is a self-biased and protected linear control current-to-duty cycle converter with an open drain output. The device operates from 6.7V to 21V at a frequency of 100kHz. It is equipped with a built-in start-up switch and thus does not require an external start-up resistor. Other features include auto-restart, overload protection, over-current protection and internal thermal shutdown protection. The DIPH package connects a single, wide lead to two ground pins.

The FSDH0165 is available now, with delivery in seven to eight weeks ARO. The device is priced at $1.50 each, in quantities of 1,000 pieces.
