?TPS6124x 3.5MHz High Efficiency Boost Converters

1 Feature 3 Description The TPS6124x device is a high-efficiency 1? Efficiency > 90%, synchronous boost DC-DC converter optimized for nominal operating conditions? V DC output voltage accuracy 5.0 ± 2% The product consists of 3 cell phones Alkaline, NiCd? Typical 30-µA quiescent current or one cell of NiMH or Li-Ion battery or Li-Polymer. The TPS6124x supports output currents up to 450 mA. The input valley current of the TPS61240 is limited to a wide VIN range of 500 ? from 2.3 V to 5.5 V mA, and the input valley current of the TPS61241 is ? the output valley current of up to 450 mA to 600 mA. ?Automatic PFM/PWM mode conversion, input voltage range 2.3 V to 5.5 V, low ripple power saving mode for improved device support battery, improve voltage efficiency in light load range, ideal for powering portable applications such as cell phones and other portable devices. • Internal Softstart, 250-µs typical start-up time The TPS6124x improves converters based on a quasi-~3.5 mhz typical operating frequency constant punctual valley current mode control scheme. In shutdown, the TPS6124x presents high impedance at the VOUT pin for current overload and thermal shutdown. This allows for use in protection applications where the output bus needs to be adjusted by another power supply to drive three surface mount external components, while the TPS6124x is required (one MLCC inductor, two ceramic off. capacitors) At light loads, the device will Automatic pulses? Skip over total solution size <13 mm2, allowing maximum efficiency at lowest quiescent current. In off mode, the current consumption is reduced to less than 1µA in the available 6-Pin DSBGA and 2mm x 2mm. The WSON package TPS6124x allows the use of a small inductor and 2 application capacitors for small solution size. During shutdown, the load is completely disconnected from the battery's USB-OTG application. The TPS6124x are available in 6-pin DSBGA and 2mm x 2mm WSON packages for portable HDMI applications. ?Mobile Phone, Smartphone Device Information (1)?pda, Handheld Computer Part Number Package Dimensions (NOM)?Portable Media Player WSON (6) 2.00 mm×2.00 mm?Digital Camera
