1. Describe

The TPS62660YFFR device is a high frequency Synchronous Buck DC-DC Converter Optimization For battery powered portable applications. on purpose For low power applications, TPS62660YFFR supports Peak load currents up to 1000 mA allow use of Low cost chip inductors and capacitors. With a wide input voltage range of 2.3 V to 5.5 V, the Device supports applications powered by Li-Ion Batteries with extended voltage range. different fixed Voltage output versions are available from 1.2 V to 2.3 volts. The TPS62660YFFR operates at a stable 6MHz switching frequency and enter power saving mode Operates at light load current to keep high efficiency over the entire load current range. PFM mode increases battery life by reducing battery life 31 μA (typ) quiescent current during illumination load and standby operation. noise sensitive application, the device can be forced into fixed Frequency PWM mode is achieved by pulling the MODE pin high. In shutdown mode, the current consumption is reduced to less than 1 μA. TPS62660YFFR in 6-pin chip scale package (DSBGA).
