The ADP2300/ADP2301 is a high efficiency, low dropout buck converter with a maximum output current of 1.2A. The input voltage range is 3.0V to 20V and the switching frequency is 700kHz (ADP2300) or 1.4MHz (ADP2301). The device uses PFM/PWM control and features low start-up current, low quiescent current, over-voltage protection, over-current protection and short-circuit protection.
The ADP2300 and ADP2301 are step‑down DC‑DC converters that operate from a 3.0 V to 20 V input and deliver up to 1.2 A of output current. The ADP2300 switches at 700 kHz, while the ADP2301 switches at 1.4 MHz, offering high efficiency up to 91 % across a wide load range.
The document contains detailed electrical characteristics, efficiency graphs, regulation data, shutdown and current‑limit specifications, as well as package dimensions for the 6‑lead TSOT package. It also provides typical application circuits and design guidelines for using the converters in various power‑management designs.
