Light-Load Algorithm Improves Efficiency of DC-DC Buck Converters from Diodes Incorporated

PLANO, Texas — (BUSINESS WIRE) — September 10, 2015 — Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the 1.5A AP65101 and 2A AP65201 synchronous DC-DC buck converters. These devices combine efficient operation with the standard pinout, space-saving TSOT26 package and are targeted toward consumer electronics, such as TVs, set-top boxes, computer monitors and home audio. These buck converters achieve maximum continuous current efficiencies up to 97%, with improved efficiency at lower loads ensured by an automatic light-load algorithm.

The AP65101 and AP65201 are designed for low-voltage regulation, especially in distributed power architectures, and operate from 4.5V to 16V inputs while delivering adjustable output voltage from 0.8V up to 80% of VIN. A low quiescent supply current and integrated high- and low-side switches with low RDS(ON) both help to reduce power loss. Protection features, including under-voltage lockout, over-current, over-voltage and over-temperature, help prevent damage to downstream components and stress-induced premature component failure. The device enable pin also has a high voltage tolerance of up to 6V.

The high level of integration and minimal need for external components combined with the small-footprint TSOT26 package provide valuable cost and circuit board space savings. Current-mode operation enables fast transient response and easy loop stabilization, while other features like programmable soft-start and a 500kHz switching frequency contribute to ease of use.
