DC/DC converters from Diodes Inc. deliver highly integrated solution for consumer applications
Diodes Inc. has introduced a pair of highly integrated synchronous DC/DC buck converters. The AP6502 and AP6503 are designed for use in consumer electronics systems such as digital TV, LCD monitors and set-top boxes, which require ultra-efficient voltage conversion.
CapaWith a switching frequency of 340kHz, and incorporating low RDSON high and low side power MOSFETS which reduce the need for external components, both devices offer an efficient, space-saving solution, particularly effective for distributed power architectures. In addition, the parts include an external, programmable soft start control input that reduces excess current during initial power-up of the application. The combination of Enable and programmable SoftStart helps in systems requiring power sequencing. Integrated Over Current Protection (OCP) and thermal shutdown features stabilize the system and ensure long-term reliability.
