They provide two • 2.25 MHz Fixed Frequency Operation independent output voltage rails powered by 1-cell • Output Current 400 mA and 600 mA Li-Ion or 3-cell NiMH/NiCD batteries. The devices are • Adjustable Output Voltage From 0.6V to V IN also suitable to operate from a standard 3.3V or 5V voltage rail. • Pin Selectable Output Voltage Supports Simple Dynamic Voltage Scaling With an input voltage range of 2.5V to 6V the TPS62400 is ideal to power portable applications like • EasyScale™ Optional One-Pin Serial Interface smart phones, PDAs and other portable equipment. • Power Save Mode at Light Load Currents With the EasyScale™ serial interface the output • 180° Out of Phase Operation voltages can be modified during operation. The fixed • Output Voltage Accuracy in PWM Mode ±1% output voltage versions TPS62401, TPS62402, • Typical 32-µA Quiescent Current for Both TPS62403 support one pin controlled simple Converters Dynamic Voltage Scaling for low power processors. • 100% Duty Cycle for Lowest Dropout The TPS6240x operates at 2.25MHz fixed switching frequency and enters the power save mode • Available in a 10-Pin QFN (3×3mm) operation at light load currents to maintain high efficiency over the entire load current range. For low noise applications the devices can be forced into • Cell Phones, Smart-phones fixed frequency PWM mode by pulling the • PDAs, Pocket PCs MODE/DATA pin high. In the shutdown mode, the • OMAP™ and Low Power DSP Supply current consumption is reduced to 1.2 µA, typical. The devices allow the use of small inductors and • Portable Media Players capacitors to achieve a small solution size. • Digital Radio • Digital Cameras The TPS62400 is available in a 10-pin leadless package (3 ×3mm QFN) 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.
