Tiny 500 mA DC-DC converter

12 November 2008 Power Electronics / Power Management

Giving portable designers the ability to add more features and functions to a handheld device, Texas Instruments announced what it claimed was the industry's smallest and thinnest 500 mA, step-down DC-DC converter solution. The high-efficiency power management IC was said to be the first 6 MHz, 500 mA converter to achieve a 13 mm² solution size with an ultra-thin 0,6 mm total height.

The TPS62601 achieves up to 89% power efficiency and only 30 μA typical operating quiescent current. The synchronous, switch-mode device's fixed frequency of 6 MHz allows the use of only one 0,47 μH inductor and two ceramic capacitors.

The converter can deliver DC voltage regulation accuracy of ±1,5% and its excellent load transient response, input voltage range of 2,3 V to 5,5 V and 1,8 V output allow it to effectively support single-rail voltage requirements.

The device 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.
