The new 20V 2 A (ADP2302) and 3 A (ADP2303) step-down, dc-to-dc switching regulators integrate a high-side MOSFET that delivers power conversion efficiencies greater than 90 percent. The devices support a wide input voltage range from 3V to 20V to accommodate a diversity of point-of-load applications, including consumer electronics and industrial and communications infrastructure equipment.
Under light loads the regulators automatically operate in PFM (pulse frequency modulation) to reduce light load losses. Other features include internal loop compensation, integrated soft-start circuitry and bootstrap diodes to enable high-density solutions for intermediate bus generation and point-of-load regulation.
The ADP2302 and ADP2303 are available in SOIC packages.
