This allows the PA to be supplied with the voltage 100% Duty Cycle for Low Dropout Operation that enables maximum power-added efficiency. Input Under-Voltage Lockout / Thermal Shutdown An integrated bypass FET automatically switches on when battery voltage drops close to the desired output 1.34 mm x 1.29 mm, 9-Bump, 0.4 mm-Pitch, voltage (V = V - 200 mV). The DC-DC switches OUT BAT Wafer-Level Chip-Scale Package (WLCSP) back to Synchronous Mode when the voltage dropout 3 MHz / 6 MHz Selectable Switching Frequency to exceeds 375 mV. The integrated bypass FET is also Facilitate System Optimization enabled when V is nominally greater than to 1.5 V. CON High-Efficiency PFM Operation at Low Power The FAN5903 offers fast transition times, enabling changes to the output voltage in less than 10 s for Sleep Mode for Very Low I Operation Q power transitions. Moreover, a Current-Mode control Up to 96% Efficient Synchronous Operation at loop with fast transient response ensures excellent line High-Power Conditions and load regulation. 10 s Output Voltage Step Response for Early Light-load efficiency is optimized by operating in PFM Power Loop Settling Mode for load currents typically less than 100 mA. The switching frequency may be set to 3 MHz or Applications 6 MHz, enabling further optimization of system performance. The FAN5903 typically uses a single, Dynamic Supply Bias for 3G/3.5G and 4G PAs small-form-factor inductor of 470 nH or 540 nH. Power Supply for WCDMA/LTE PAs Efficiency may be further optimized using a 1.0 H inductor when running at 3 MHz. Resources When output regulation is not required, the FAN5903 may be placed in Sleep Mode by setting V nominally CON For more information or a full copy of this datasheet, to 50 mV. This ensures a very low I (<70 A) while Q please contact a Fairchild representative. enabling a fast return to output regulation. The FAN5903 enables significant current reduction and increased talk time and is available in a 1.34 mm x 1.29 mm, 9-bump, 0.40 mm-pitch, WLCSP package.
