Diodes Incorporated’s DC/DC Converters Increase Efficiency

PLANO, Texas — (BUSINESS WIRE) — May 5, 2011 — 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 AP6507 and AP6508 synchronous DC/DC buck converters. Delivering a continuous load current of up to 3A, the AP6507 and AP6508 converters offer designers of distributed power systems an operating efficiency as high as 90%. With input voltage ranges of 4.5V to 18V and 4.5V to 21V respectively, these compact converters will support the needs of low voltage 5V and 12V bus systems in a broad range of consumer electronic products, including monitors, LCD TV and set-top box.

Using a simple external resistor divider, the adjustable output of the DC/DC converters can be set to any voltage down to as low as 0.8V. To meet demands for increased power densities, the converters are provided in space-saving exposed pad package options: the AP6507 in SO-8EP, and the AP6508 in DFN4030-14EP.

By operating at a high switching frequency of 500kHz, the converters can also make use of smaller external components. That smaller footprint along with the devices’ integration of high- and low-side MOSFET switches, internal compensation and protection features, enables significant system board space savings.

The integrated overcurrent protection and thermal shutdown features of both DC/DC converters combine to increase system stability and achieve long-term reliability. Additional features provided by the AP6508 are an externally programmable soft-start function and a power good flag, enabling the implementation of power sequencing and ramp control.
