MAX8896 Dual buck converter po
max8896 dual buck converter powers the wcdma pa and rf transceiver to extend battery life in 3g handsets
tiny, dual step-down converter integrates dc-dcs for both pa and rf transceiver.
maxim's dual buck converter integrates a 700ma dc-dc for powering the 3g pa and a 200ma dc-dc for the rf transceiver in a tiny 4mm² package.
sunnyvale, ca—february 17, 2010—maxim integrated products (nasdaq: mxim) introduces the max8896, a dual step-down converter designed for powering wcdma/ncdma pa (power amplifier) modules and rf transceivers. this 4mm² device integrates a high-efficiency, pa step-down converter that is optimized for medium- and low-power transmission, and includes a bypass fet for powering the pa directly from the battery during high-power transmission. by using the max8896 between the battery and rf-transceiver/pa, designers can reduce current consumption by up to 50% under typical operating conditions, thus extending battery life. the max8896 also includes an rf step-down converter that supplies a high-psrr, low-noise ldo (low-dropout linear voltage regulator) to provide a high-efficiency voltage supply for the rf transceiver. the max8896 is well suited for multiband wcdma/ncdma applications such as cellular handsets, netbooks, and smartphones. the max8896 is available in the infineon® smarti™ ue hspa rf transceiver and the xmm™ 6160 mobile phone platform, providing users with best-in-class battery life.
supporting 1.9a of peak current, the integrated low-impedance 140mω (typ) bypass fet provides maximum power with minimum dropout, even under low-battery conditions. during high-power transmission, the bypass fet automatically turns on if the required output voltage is within 99% of the input voltage, and the pa step-down converter is forced into a 100% duty cycle.
the rf step-down converter has 94% peak efficiency with a 2mhz fixed switching frequency. it supports a 100% duty cycle, and provides a fixed 3.1v output voltage with ±2% output-voltage accuracy. the high-psrr (65db), low-noise (16µvrms), 2.8v ldo delivers a guaranteed 200ma output current. the low-noise output makes this ldo ideal for rf transceiver biasing or applications that require an exceptionally clean power source.
the max8896 is offered in a tiny, 2mm x 2mm, 16-bump ucsp™ package (0.7mm height, max) and is fully specified over the -40°c to +85°c extended temperature range. prices start at $1.92 (2500-up, fob usa). samples and evaluation kits are available upon request.
maxim integrated products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. the company was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers' products. to date, it has developed over 6200 products serving the industrial, communications, consumer, and computing markets.
