DC/DC converters from Diodes Incorporated increase efficiency

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 and combined with the integration of high- and low-side MOSFET switches, internal compensation and protection features, enable significant PCB 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.
