1.2 A, 20 V, 700 kHz Nonsynchronous Step-down Switching Regulator
The ADP2300/ADP2301 are compact, constant-frequency, current-mode, step-down dc-to-dc regulators with integrated power MOSFET. The ADP2300/ADP2301 devices run from any input voltage from 3.0 V up to 20 V, making them suitable for a wide range of applications. A precise, low voltage internal reference makes these devices ideal for generating a regulated output voltage as low as 0.8 V, with ±2% accuracy, for up to 1.2 A load current.
There are two frequency options: the ADP2300 runs at 700 kHz and the ADP2301 runs at 1.4 MHz. These options allow users to make decisions based on the trade-off between efficiency and the size of the total solution. Current-mode control provides fast and stable line and load transient performance. Each ADP2300/ ADP2301 device includes an internal soft start to prevent inrush current at power up. Other key safety features include short-circuit protection, thermal shutdown (TSD) and input undervoltage lockout (UVLO). Precision enable pin threshold voltage allows ADP2300/ADP2301 to be easily sequenced from other input/ output supplies, or the enable pin can be used as a programmable UVLO input by using resistive divider.
The ADP2300/ADP2301 are available in a 6-lead TSOT package and are rated for the −40°C to +125°C junction temperature range.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The ADP2300/ADP2301 are compact, constant-frequency, current-mode, step-down dc-to-dc regulators with an integrated power MOSFET. The ADP2300/ADP2301 evaluation boards are complete solutions that allow the user to evaluate the performance of the regulators. There are two frequency options available: the ADP2300 runs at 700 kHz, and the ADP2301 runs at 1.4 MHz. These options allow the user to make design decisions based on the trade-off between efficiency and the size of the total solution.
The ADP2300/ADP2301 provide accurate (±2%) output regulation for load currents up to 1.2 A. Current-mode control provides fast and stable line and load transient performance. The precision, EN pin, threshold voltage allows the ADP2300/ADP2301 to be sequenced from other input/output supplies. The EN pin can also be used as a programmable UVLO input by using a resistive divider.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
