Featured Products
A4490
The A4490 efficiently powers multiple voltage rails with its three integrated buck converters, independent soft-start, and multiphase switching for reduced EMI. Ideal for industrial and portable equipment.
A4491
Designed to provide the power supply requirements of printers, office automation, industrial, and portable equipment, the A4491 provides three high current, high performance, switching regulator outputs in a single package, saving space, cost and component count.
A8601
The A8601 is a fixed frequency, multiple-output supply for LCD bias
A8651
The A8651 is an adjustable frequency, high output current, PWM regulator that integrates a high-side, P-channel MOSFET and a low-side, N-channel MOSFET. The A8651 incorporates current-mode control to provide simple compensation, excellent loop stability, and fast transient response.
