The TPS61230 is a high efficiency synchronous boost converter with 5-A switch. This device has a compact size and is optimized for products powered by a one-cell Li-Ion battery, or a regulated power ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

The synchronous architecture of Magnachip’s boost converter achieves both high efficiency and low quiescent current. By using low-resistance high-side and low-side synchronous switches, the boost ...

Many portable devices use LCD displays. These displays need large positive and negative power supplies, but most mobile devices have power rails at 5 V, 3.3 V or even lower. Thus, the challenge is not ...
