Diodes Incorporated Unveils DC-DC Buck Converters Enable Best-In-Class EMI Performance

diodes logoDiodes Incorporated announces the AP63200/AP63201/AP63203/AP63205 2A synchronous DC-DC buck converters.

Diodes incorporated new DC-DC buck converters deliver class-leading EMI performance across a range of input and output voltages.

Switching DC-DC converters can typically introduce significant EMI to a design. The AP63200/AP63201/AP63203/AP63205 employ:

  • A frequency spread spectrum (FSS) technique with a switching frequency jitter of ±6%, and proprietary gate driver technology to enable the industry’s best-in-class EMI performance.
  • This design supports single layer layout and can remove the need for vias to further reduce EMI.
  • Further improvements are achieved through the proprietary gate driver design, which reduces switching node ringing without sacrificing MOSFET turn-on and turn-off times.
  • 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/AP63205 deliver excellent efficiencies of up to 88% under light-load conditions (5mA output current), and a quiescent current as low as 22µA.
  • 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.

Applications

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.

Availability and Packaging

All products are available in the TSOT26 package.
