Step-down converter

17 August 2011 Power Electronics / Power Management

Texas Instruments has introduced a 3 MHz, 100 mA synchronous step-down DC/DC converter which integrates a bypass switch and a unique DCS-Control technology. The device has an operating current of only 25 μA and supports many low-power applications, such as Bluetooth low-energy systems, metering and building technologies, mobile phones, consumer electronics, medical and human interface devices.

The TPS62730 achieves 95% conversion efficiency and reduces current consumption drawn from the battery in transmit and receive modes. The device’s low-power bypass switch only consumes 30 nA of current for sleep and low-power modes. The converter also generates less than 15 mVpp typical output voltage ripple, providing low noise to low-power RF applications.

DCS-Control technology is an advanced regulation topology that combines the advantages of hysteretic and voltage mode control within a single device, enabling excellent AC line and transient load regulation. The feature provides a seamless transition between high-load and light-load (power save) operation. An additional voltage feedback loop also ensures DC accuracy.
