New from Texas Instruments is a synchronous, 28 V, 500 mA step-down DC-DC converter that can operate at less than 5 μA during sleep mode.
The new TPS62175 maintains high efficiency during light load operation, while supporting ultra-low power microcontrollers that operate in 12 V, 15 V and 24 V applications such as industrial sensor, smart meter, medical and wireless power transmission designs.
The device achieves greater than 70% efficiency at 100 μA and operates from just 20 μA typically in regular mode. It requires only three external components and comes in a 2 x 3 mm WSON package with a 68 mm² total solution size.
The TPS62175 features TI’s patented DCS-Control regulation topology, which combines hysteretic and voltage-mode control in a single device, resulting in excellent AC line and transient load regulation. DCS-Control also provides DC accuracy through a voltage feedback loop, and creates a seamless transition between high- and light-load (power save) operation.
