Step-down converters are high efficiency and easy to use

Stocked by Mouser, Texas Instruments TPS62135/TPS621351 step-down converters are high efficiency and easy to use synchronous step-down DC-DC converters, based on the DCS-Control Topology. The device has a wide input voltage range of 3V to 17V which makes them suitable for multi-cell Li-Ion as well as 12V intermediate supply rails. Each device provides 3.5A continuous output current. The device automatically enters power save mode at light loads to maintain high efficiency across the whole load range. With that, these are well suited for applications that require connected standby performance, like ultra-low-power computers. With the MODE pin set to low, the switching frequency of the device is adapted automatically based on the input and output voltage. This technique is called Automatic Efficiency Enhancement (AEE) and maintains high conversion efficiency over the whole operation range. It provides a 1% output voltage accuracy in PWM mode and therefore enables the design of a power supply with high output voltage accuracy.
