Both devices are available in a thermally enhanced DFN3x3 exposed pad package, delivering an output current of 2A and 3A, respectively. The devices offer a low on-resistant power stage, allowing cooler power conversion for a variety of consumer electronics application such as LCD TVs, set-top boxes, as well as DVD players and recorders.
The low on-resistance of the internal power MOSFETs in these devices allows higher efficiency and less heat generation. They have over 90 percent efficiency at full load operation and maintain at 87 percent efficiency while in 10mA light load operation.
When operating in low output current conditions, the device will run in a proprietary pulse energy mode (PEM) to obtain high efficiency. Under heavy load steady-state conditions, the device will operate in a fixed frequency and Continuous-Conduction Mode (CCM).
The small standby current combined with a thermally enhanced package achieves better efficiency and thermal performance over the previous generation solution
