Description
The AP6507 is a 500kHz switching frequency internal
compensated synchronous DCDC buck converter. It has
integrated compensation, and low R
DSON
high and low side
MOSFETs.
The AP6507 enables continues load current of up to 3A with
efficiency as high as 93%.
The AP6507 features current mode control operation, which
enables fast transient response times and easy loop
stabilization.
The AP6507 simplifies board layout and reduces space
requirements with its high level of integration and minimal
need for external components, making it ideal for distributed
power architectures.
The AP6507 is available in a standard Green SO-8EP
package with exposed PAD for improved thermal
performance and is RoHS compliant.
