Tiny 6 MHz step-down converter

4 February 2009 Power Electronics / Power Management

Texas Instruments recently announced a tiny 500 mA, step-down DC-DC converter solution for space-constrained applications.

The high-efficiency power management IC is a 6 MHz, 500 mA converter achieving a 13 mm² solution size with an ultra-thin 0,6 mm total height.

Leveraging TI’s analog manufacturing technology, the new TPS62601 achieves up to 89% power efficiency and only 30 μA typical operating quiescent current – all from a 0,9 mm x 1,3 mm chip scale package roughly the size of a flake of pepper. The synchronous, switch-mode device’s fixed frequency of 6 MHz allows the use of only one 0,47 μH inductor and two low-cost ceramic capacitors.

The device can deliver DC voltage regulation accuracy of ±1,5%. In addition, its excellent load transient response, wide input voltage range of 2,3 V to 5,5 V and 1,8 V output allows it to support single-rail voltage requirements as designers add new features and functionality. It supports many applications, such as memory modules, GPS modules, Bluetooth and Wi-Fi modules or other wireless micro-modules.

The converter also applies energy-saving techniques to help maximise battery run-time. For example, it automatically enters a power save mode during light-load operating conditions via an automatic pulse frequency modulation and pulse width modulation switching feature. In shutdown mode, the device’s current consumption is reduced to less than 1 μA.
