DCDC Regulators

Wide Input Voltage, 3.5A Adjustable Buck Regulator with Programmable Frequency

A8586

The A8586 delivers efficient step-down conversion with a wide input voltage range (3.8V-36V), adjustable output voltage (0.8V-30V), and programmable switching frequency up to 4 MHz. Integrated MOSFET and current-mode control simplify design.
