Micrel: Micrel Showcases Industry's Coolest, Low-Power Green Power Solutions at APEC '09
WASHINGTON, DC--(Marketwire - February 16, 2009) - Micrel Inc., (
Industry's Highest Matching Linear WLED Drivers, Micrel's [ MIC284x ] Family
This new family of efficiency linear White LED (WLED) drivers extends the need for battery power in mobile applications up to an astounding 32 percent. The [ MIC284x ] solutions are aimed at a wide variety of mobile devices including portable display backlights, keypad backlighting and camera flash in mobile devices, mobile handsets, digital cameras, portable media/MP3 players, portable navigation devices (GPS) and other portable devices -- all applications where saving battery power is critical.
High Efficiency 7A Integrated Synchronous Buck (Step-Down) Regulator, MIC22700
The MIC22700 is a high efficiency 7A integrated synchronous buck (step-down) regulator optimized for the highest efficiency. It achieves more than 95 percent efficiency, while still switching at 1MHz over a broad load range with only 1µH inductor and a 47µF output capacitor. It also features built-in sequencing, tracking and ramp control -- enabling all power-up sequencing and tracking protocols. The solution is ideal for high power density point-of-load conversion, servers and routers, DVD recorders, computing peripherals, base stations, FPGAs, DSP and low voltage ASIC power applications.
Extreme Efficiency 1.5A HyperLight Load Buck Converter, MIC23150
Micrel's 1.5A HyperLight Load™ Regulator supports green home/office appliances and handheld products, enabling the Company to continue its green initiative with Power saving, 'Green' Devices.
The [ MIC23150 ] is the highest output current device in the popular HyperLight Load™ family of synchronous step-down regulators. The patented architecture implemented in the MIC23150 delivers extremely high efficiency light load for portable products and green home/office appliances. The [ MIC23150 ] features internal MOSFETs able to deliver up to 1.5 Amps output current while consuming just 23 Micro Amps of quiescent current inside a tiny 2mm x 2mm Thin MLF® package. As with many other members of the HyperLight Load™ family of step-down regulators, the [ MIC23150 ] achieves up to 93 percent peak efficiency and an impressive 87 percent efficiency under a 1mili Amp load.
RF Low-Power, Low Cost Receiver, [ MICRF219 ]
Micrel's [ MICRF219 ] is a 300MHz to 450MHz super-heterodyne, image-reject, RF receiver with Automatic Gain Control, OOK/ASK demodulator and analog RSSI output. It only requires a crystal and a minimum number of external components to implement. It is ideal for low-cost, low-power, RKE, TPMS, and remote actuation applications and achieves -110dBm sensitivity at a data rate of 1kbps (Manchester encoded. The device operates from a supply voltage of 3.0V to 3.6V, and consumes just 4.0mA of supply current at 315MHz and 6.0mA at 433.92MHz. A shutdown mode reduces supply current to 0.5uA. The Auto-Polling feature allows the [ MICRF219 ] to sleep and poll for user defined periods, thus further reducing supply current. During normal operation, an optional Squelch feature disables the data output until valid bits are detected.
RF Remote Control Packet Encoder, [ MICRF302 ]
Micrel is rolling out the [ MICRF302 ] RF Remote Control Packet Encoder. It offers a low-cost, low-power, microcontroller replacement for remote control applications, such as fan and lighting control, thermostats, home automation, toys, low-tier RKE and garage door openers. The device dramatically reduces power consumption by consuming only 0.5uW in standby mode while awaiting a push-button closure and consumes just 230uW of power while transmitting a packet.
"With billions of consumer electronics and office products sold every year and energy conservation fast moving from a worldwide concern into crisis mode, it was crucial that the next generation of ICs offer breakthrough approaches to saving power. Micrel's Green initiative involves all aspects of design, engineering, marketing and other disciplines to bring to market exceptional and innovative methods for saving power," noted Andrew Cowell, Micrel's vice president of marketing for analog products. "These new devices demonstrate Micrel's on-going commitment to providing its customers the most innovative and advanced ICs on the market today. APEC provides Micrel with a synergistic and complementary venue for showcasing its commitment to green strategies and Corporate product development."
