ON Semiconductor Drives Power Efficiency and Protection in Portable and Consumer Electronics with New High Performance Devices

Electronica 2012 – New Portable and Consumer Product Launches

ON Semiconductor debuts two new single-channel power MOSFETs for low voltage drive switching at this year’s Electronica tradeshow and conference. The new MCH3383 P-channel MOSFET has a drain-to-source voltage (VDSS) of 12 volts (V) and a drain current (ID) of 3.5 amperes (A) with an on-state resistance (RDS(ON)) of 69 milliohms (mΩ), while the MCH3484 N-channel MOSFET has a VDSS of 20 V, an ID of 4.5 A and an RDS(ON) of 330 mΩ. These devices are highly suited to use in IC recorders and smartphones.

The NCP4545, NCP45520/21, and NCP45524/25, also being introduced at the event, are new members of ON Semiconductor’s ecoSWITCH family of highly compact, advanced load management solutions for efficient power domain switching. Combing control and drive functionality, these devices each have soft-start via adjustable slew rate control and integrate a low RDS(ON) power MOSFET plus a charge pump. They are suitable for notebook/tablet computers, portable medical equipment, enterprise computing systems, hot swap devices, peripheral ports, telecom and industrial equipment and various portable devices.

Additionally, the NCP333, NCP334, NCP335, NCP336, and NCP337 are newly introduced cost-effective, ultra-compact, high performance load switches. Covering a 1.2 V to 5.5 V input voltage range, these MOSFET-based devices each have a built-in output discharge path to eliminate residual voltages on the output rail. They are optimized for use in cell phones, notebook/tablet computers and digital cameras.

Lastly, the NCP702, NCP703 and NCP729 are low drop-out (LDO) linear voltage regulators with a 2.0 V to 5.5 V input voltage range, ultra-low quiescent current and built-in thermal shutdown mechanism. These devices’ superior performance characteristics make them highly optimized for noise-sensitive applications, where signal integrity must be maintained, such as phase locked loops, oscillators, frequency synthesizers and low noise amplifiers. Among the end products they will prove particularly suited to inclusion in are smartphones, digital cameras, tablet computers, portable DVD/media players, wireless headsets, wifi boards and portable GPS systems, as well as portable medical equipment.
