TPS62147RGXR Product Details

Texas Instruments TPS62147/TPS62148 Step-Down Converters 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 3V to 17V make them suitable for multi-cell Li-Ion as well as 12V intermediate supply rails. The devices provide 2A continuous output current. Each device automatically enters Power Save Mode at light loads to maintain high efficiency across the whole load range. This makes them 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 provides 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 setting a switching frequency in forced PWM mode of 1.25 MHz or 2.5 MHz, respectively.

Description

The TPS62147 and TPS62148 are high efficiency and easy-to-use synchronous step-downDC/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 aswell as 12-V intermediate supply rails. The devices provide 2-A continuous output current. Theyautomatically enter Power Save Mode at light loads to maintain high efficiency across the wholeload range. With that, they are well suited for applications that require connected standbyperformance, like industrial PC and video surveillance. With the MODE pin set to low, the switchingfrequency is adapted automatically based on the output current and also on input and outputvoltage. This technique is called Automatic Efficiency Enhancement (AEE?) and maintains highconversion efficiency over the whole operation range. TPS62147, TPS62148 provide a 1% outputvoltage accuracy in PWM mode and therefore enable the design of a power supply with high outputvoltage accuracy. The FSEL pin allows to set a switching frequency in forced PWM mode of 1.25 MHzor 2.5 MHz, respectively.

The typical quiescent current is 18 μA. In shutdown mode the current is typically 1μA.

The devices are available as an adjustable version, packaged in a 3-mm × 2-mm VQFNpackage.
