Power Supply Unit features smart fan operation.

2015-02-18 14:30:41| Industrial Newsroom - All News for Today

Rated from 500–600 W, MVP (Most Value Power) series accepts 90–264 V input range, offers 86% efficiency at typical load, and complies with Intel ATX 12 V v2.31 and EPS 12 V v2.92. Cooling fan delivers silent cooling with intelligent temperature control, and active PFC (PF>0.99) is standard. Product delivers 40 A single +12 V output (up to 90% power available on +12 V rail), and included OVP, UVP, OPP, OTP, and SCP prevent damage. Hybrid cable management provides clear interface.

Motor Control Pre-Driver IC enables quiet low-power fan operation.

2015-02-18 14:30:40| Industrial Newsroom - All News for Today

Accommodating 3.5–30 V input, TC78B006 series comprises single-phase brushless DC (BLDC) motor control pre-driver ICs available in 5.5 x 6.4 mm SSOP16 or 3 x 3 mm QFN16 package. PWM voltage and pseudo sine-wave current driving functions promote efficient and quiet cooling fan operation in data servers and home appliances, while automatic standby function reduces power consumption when fan is not in use. Additionally, IC can drive 2 external high-side Pch and 2 low-side Nch MOSFETs.

Knicks owner James Dolan calls criticizing fan 'alcoholic maybe,' urges him to root for Nets

2015-02-09 02:04:01| Telecom - Topix.net

Madison Square Garden chairman James Dolan responded to a Knicks fan who had criticized him with an email wondering if the man is an alcoholic and telling him to root for the Nets instead. An MSG spokesman confirms the email, which appeared Sunday on Deadspin.com , was written by Dolan, who is also president and CEO of Cablevision Systems Corp. The criticism of Dolan was sparked by the poor performance of the Knicks, which are 10-41 on the season.

Low-Noise Single Coil Fan Driver IC has built-in current limiting.

2015-01-27 14:33:24| Industrial Newsroom - All News for Today

Promoting energy efficient cooling system designs, 600 mA MLX90297 integrates Hall Effect sensor with 2 half bridge output stages. In addition to minimum speed setting, speed curve can be tuned via inclusion of one extra resistor. Soft start and soft switching mechanisms achieve optimal acoustic noise levels, as well as minimal vibration at higher speeds, without sacrificing max motor torque, and reduced driver resistance (RDSon) allows application to fans with coil resistances <10 Ω.
