♠ 1.2 A, 20 V, 700 kHz/1.4 MHz, Nonsynchronous Step-Down 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 input voltages of 3.0 V 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 total solution size. Current-mode control provides fast and stable line and load transient performance. The ADP2300/ADP2301 devices include 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). The precision enable pin threshold voltage allows the ADP2300/ADP2301 to be easily sequenced from other input/ output supplies. It can also be used as a programmable UVLO input by using a 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.
