High-frequency DC-DC converter reduces external components required

9 August 2006 Power Electronics / Power Management

STMicroelectronics has introduced an advanced high-frequency step-down DC-DC converter for applications that require high efficiency, small size, and light weight. The new ST1S06 integrates functions that benefit users with superior electrical performance while minimising the need for external components. The ST1S06 includes a synchronous rectification block to avoid the use of an external Schottky Diode while improving the device's efficiency up to 95%. Other key features include an output current capability of 1,5 A maximum over all operating conditions, a high switching frequency of 1,5 MHz and good stability. The high frequency performance allows the device to operate with a small inductor, while the high stability permits the use of small, low-ESR, ceramic capacitors. As a result, the chip requires only a few external components to operate: the small inductor, two capacitors and, for the adjustable version, two resistors. The ST1S06 is offered with fixed output voltages, or in the adjustable version that, using an external resistor divider, generates an output voltage adjustable from 0,8 V feedback voltage. The device comes in the 3 x 3 mm DFN6 Ecopack package.
