GENERAL DESCRIPTION

The ADP2302/ADP2303 are fixed frequency, current-mode control, step-down, dc-to-dc regulators with an integrated power MOSFET. The ADP2302/ADP2303 can run from an input voltage of 3.0 V to 20 V, which makes them suitable for a wide range of applications. The output voltage of the ADP2302/ADP2303 can be down to 0.8 V for the adjustable version, while the fixed output version is available in preset output voltage options of 5.0 V, 3.3 V, and 2.5 V. The 700 kHz operating frequency allows small inductor and ceramic capacitors to be used, providing a compact solution. Current mode control provides fast and stable line and load transient performance.
