Q1: What are the main features of AP64501SP-13?
A1: AP64501SP-13 is a 5A synchronous buck regulator with a 3.8V to 40V input range and an adjustable output starting from a 0.8V reference. It operates at a typical 570kHz switching frequency and integrates high side and low side power MOSFETs. It also provides programmable soft start, low quiescent current, frequency spread spectrum, low dropout mode, undervoltage lockout, output overvoltage protection, cycle by cycle current limiting, and thermal shutdown. The device is housed in an 8-SO-EP package.
Q2: What is AP64501SP-13 used for?
A2: AP64501SP-13 is designed for step down DC to DC power conversion where a stable lower voltage rail is required from a higher input supply. Typical applications include 5V, 12V, and 24V distributed power supplies, point of load converters, network systems, consumer electronics, home audio equipment, power tools, laser printers, and small appliances. Its integrated MOSFETs and EMI reduction features help simplify compact power supply designs.
Q3: Does AP64501SP-13 have any alternative manufacturer and part number?
A3: There is no guaranteed drop in replacement that can be considered a direct substitute without checking the complete circuit design. Similar 5A buck regulators include Texas Instruments TPS54560BQPWPRQ1, which supports a higher 60V input rating, and other synchronous buck regulators from manufacturers such as Monolithic Power Systems. However, differences in pin configuration, package, input voltage, switching frequency, control method, compensation, protection functions, and thermal characteristics mean that these alternatives should be evaluated before replacement.
Q4: Is technical support available for AP64501SP-13?
A4: Yes.
