Both step-down converters enter a 6 V low power mode at light load for maximum efficiency • 2.25-MHz Fixed Frequency Operation across the widest possible range of load currents. • Power Save Mode at Light Load Current For low noise applications the devices can be forced into fixed frequency PWM mode by pulling the • 180° Out-of-Phase Operation MODE pin high. Both converters allow the use of • Output Voltage Accuracy in PWM mode ±1% small inductors and capacitors to achieve a small • Total Typical 32-µA Quiescent Current for solution size. TPS65053 provides an output current Both DC/DC Converters of up to 1A on the DCDC1 converter and up to 0.6A on the DCDC2 converter. The TPS65053 also • 100% Duty Cycle for Lowest Dropout integrates one 400mA LDO and two 200mA LDO • One General-Purpose 400-mA LDO voltage regulators, which can be turned on/off using • Two General-Purpose 200-mA LDOs separate enable pins on each LDO. Each LDO • V IN Range for LDOs from 1.5 V to 6.5 V operates with an input voltage range between 1.5V and 6.5V allowing them to be supplied from one of • Available in a 4 mm x 4 mm 24-Pin QFN the step-down converters or directly from the main Package battery. LDO1 and LDO2 are externally adjustable while LDO3 has a fixed output voltage of 1.3V. The TPS65053 comes in a small 24-pin leadless • Cell Phones, Smart-Phones package (4mm × 4mm QFN) with a 0.5mm pitch. • WLAN • PDAs, Pocket PCs, GPS • OMAP™ and Low-Power DSP Supply • Portable Media Players • Digital Cameras Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
