Diodes Incorporated, a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today announced the availability of the AP63200, AP63201, AP63203, and AP63205 2A synchronous DC-DC buck converters, delivering class-leading EMI performance across a range of input and output voltages. These devices are well-suited for a number of applications, including home appliances and industrial electronics, as well as telecommunications, power tools, office equipment and consumer products such as TVs and STBs.
Switching DC-DC converters can typically introduce significant EMI to a design. However, the AP63200/AP63201/AP63203/AP6320
The fully integrated devices feature high-side and low-side MOSFETs with very low on-resistance, RDS(ON), complemented by Diodes’ proprietary gate driver technology and compensation network. By employing pulse frequency modulation (PFM), the AP63200/AP63201/AP63203/AP6320
The wide input voltage range of between 3.8V to 32V supports a variable output voltage of between 0.8V to VIN (AP63200/AP63201) or fixed output voltages of 3.3V (AP63203) or 5V (AP63205). All devices can deliver a maximum continuous output current of 2A. The AP63200/AP63201 devices can also operate as an LDO regulator by employing a duty cycle of 100%, providing a stable output voltage to within 1% of an unregulated input voltage. All of the devices have been designed to withstand input voltage surges of up to 40V for 400ms.
All products are available in the TSOT26 package and priced at $0.60 each in 1000 piece quantities.
