More Information

The TPS62147 and TPS62148 are high efficiency and easy-to-use synchronous step-down DC/DC converters, based on the DCS-Control™ Topology. The wide input voltage range of 3-V to 17-V make them suitable for multi-cell Li-Ion as well as 12-V intermediate supply rails. The devices provide 2-A continuous output current. They automatically enter Power Save Mode at light loads to maintain high efficiency across the whole load range. With that, they are well suited for applications that require connected standby performance, like industrial PC and video surveillance. With the MODE pin set to low, the switching frequency is adapted automatically based on the output current and also on input and output voltage. This technique is called Automatic Efficiency Enhancement (AEE™) and maintains high conversion efficiency over the whole operation range. TPS62147, TPS62148 provide a 1% output voltage accuracy in PWM mode and therefore enable the design of a power supply with high output voltage accuracy. The FSEL pin allows to set a switching frequency in forced PWM mode of 1.25 MHz or 2.5 MHz, respectively.
