Micrel Extends Performance and Saves Cost With New Synchronous Hyper Speed Control(TM) Family of PWM Controllers
(Thomson Reuters ONE) - New Architecture Dramatically Reduces Output Capacitance and FeaturesExcellent Transient Response for High Delta V OperationSAN JOSE, CA -- (MARKET WIRE) -- 07/02/09 -- Micrel Inc., (NASDAQ:MCRL), an industry leader in analog, high bandwidth communicationsand Ethernet IC solutions, today introduced the first members of thefamily of Hyper Speed Control(TM) PWM controllers, the MIC2164,MIC2164-2 and MIC2164-3. The IC's Hyper Speed Control(TM)architecture significantly reduces the required output capacitanceand allows for excellent transient response, while making high deltaV operation (VIN=28V, VOUT=0.8V) possible. The solutions are idealfor set-top boxes, gateways, routers, computing peripherals, andtelecom/networking equipments. The MIC2164 is currently availablein volume quantities with pricing starting at $0.72 for 1K quantitieswhile MIC2164-2 and MIC2164-3 are priced at $0.77 and $0.82 for 1Kquantities respectively. Samples can be ordered on line at:http://www.micrel.com/ProductList.do."Micrel's unique Hyper Speed Control(TM) architecture offers terrificbenefits such as reduced BOM cost and world class transient responsefor cost-sensitive applications such as set-top-box, graphic cardsand servers," stated John T. Lee, director of power products, Micrel."The huge advantage gained by our digitally modified hyper speedarchitecture is high speed, resulting in a smaller footprint andlower system-level cost for our customers."Micrel's new devices are constant on-time mode PWM controllers thatfeature wide input voltage range, high performance, and are capableof driving up to 25A of load current. The MIC2164 operates at300kHz PWM frequency while MIC2164-2 and MIC2164-3 operate at 600kHzand 1MHz respectively, to allow a size reduction path. The familyachieves greater than 95 percent efficiency, while still switching athigh frequencies, over a broad load range. The MIC2164 Hyper SpeedControl(TM) family of PWM controllers operates over a wide inputsupply range of 3V to 28V and also offers cycle-by-cycle currentlimiting for FET protection. While the UVLO circuitry ensures properoperation under power-sag conditions to prevent the MOSFETs fromoverheating, the Soft Start feature reduces the inrush current. Italso features built-in compensation with an external ripple injectioncircuit. The MIC2164 Hyper Speed Control(TM) family of PWMcontrollers is available in a 10-pin MSOP package with a junctionoperating range from -40degC to +125degC.
