NXP Announced GreenChip Power ICs

Published:2012/2/8 21:18:00 Author:Phyllis From:SeekIC

NXP Semiconductors recently unveiled the GreenChip™ SPR TEA1716 switched-mode power supply (SMPS) controller IC and several highly cost-effective SPF (smart power flyback) ICs. The company also expanded its TEA172x family and announced a new GreenChip synchronous rectification (SR) control IC.

The new GreenChip ICs are designed for chargers, adapters and power supplies across a broad range of applications, which include mobile communication devices such as smartphones and media tablets; portable computing devices such as e-readers, audio/video players, netbooks, Ultrabooks™ and PC peripherals; white goods such as washing machines, refrigerators, dishwashers and induction cookers; and industrial and residential systems for smart lighting, smart metering, HVAC, and home and building automation and control.

NXP’s new GreenChip SPR TEA1716 is ahead of the curve in driving low-load standby power down to half a watt and below, and is now sampling with lead customers developing power adapters that will meet the new EuP Lot 6 requirements.

The GreenChip SPR TEA1716 is a power factor correction (PFC) and LLC resonant combo converter featuring energy-saving operating modes that will help designers meet and exceed very stringent no-load and low-load standby requirements. Designed for use in 90-W to 500-W power supplies, the smart power resonant (SPR) TEA1716 combines PFC and a resonant half-bridge controller (HBC) in a SO24 package. With no-load power levels under 150 mW and an average efficiency of more than 91 percent over universal mains, the TEA1716 sets a new benchmark for standby efficiency as the first combo controller available today to enable standby consumption well below 0.5 watt at a load of approximately 250 mW, as specified under the EU Energy Using Products Directive (EuP) Lot 6.

The TEA1731 is one of several new GreenChip smart power flyback ICs from NXP which are highly integrated, reduce the number of external components required, and are available in very small packages to enable the miniaturization of adapters and power supplies, thus minimizing the total bill of materials. These cost-effective GreenChip SPF ICs also feature a complete set of protections to help maximize reliability.

NXP’s new GreenChip TEA1792T/TEA1792TS is a 6-pin synchronous rectification controller capable of driving a wide range of SR MOSFETs of all brands to the lowest possible RDS(on). Available in a TSOP6 package, the TEA1792 SR control IC requires minimal external components and reduces PCB real estate for the syncrec function significantly. Pairing the GreenChip TEA1792 alongside NXP’s power SR MOSFETs in LFPAK, which offers automotive-grade ruggedness, enables high power density for very small charger designs. Other available packages for NXP’s broad selection of Power MOSFETs include TO220, I2PAK and D2PAK.
