Delivering a continuous load current of up to 3 A, the AP6507 and AP6508 synchronous DC-DC buck converters from Diodes Incorporated offer designers of distributed power systems an operating efficiency as high as 90%. With input voltage ranges of 4,5 V to 18 V and 4,5 V to 21 V respectively, the converters will support the needs of low-voltage 5 V and 12 V bus systems in a broad range of consumer electronic products including monitors, LCD TVs and set-top boxes.
Using a simple external resistor divider, the adjustable output of the devices can be set to any voltage down to 0,8 V. 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 500 kHz, they 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 over-current 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.
