ADP2303ARDZ

The ADP2303ARDZ from Analog Devices is a fixed-frequency, current-mode control, step-down DC-to-DC regulator featuring an integrated power MOSFET. It supports a wide input voltage range from 3.0 V to 20 V, making it suitable for various applications. This device can provide a maximum load current of 3 A.

The regulator operates at a 700 kHz switching frequency, which enables the use of small inductors and ceramic capacitors for a compact solution. It offers ±1.5% output accuracy over temperature and an adjustable output voltage down to 0.8 V. Key features include integrated soft-start circuitry to manage inrush current, undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD).

The ADP2303ARDZ is available in an 8-lead SOIC package with an exposed paddle, designed for surface mount applications. Its current-mode control architecture ensures fast and stable line and load transient performance. The power-good signal can be utilized for sequencing other devices, and the precision enable pin with hysteresis allows for easy sequencing from other supplies.

Applications for the ADP2303ARDZ include intermediate power rail conversion, DC-to-DC point-of-load applications, and use in communications, networking, industrial, instrumentation, healthcare, and consumer electronics.
