ADP2303ARDZ-R7

The ADP2303ARDZ-R7 from Analog Devices is a fixed-frequency, current-mode control, step-down DC-DC regulator. It is designed to operate from an input voltage range of 3.0 V to 20 V and can deliver a maximum load current of 3 A. This device features an adjustable output voltage down to 0.8 V, providing flexibility for various power management applications.

With a switching frequency of 700 kHz, the ADP2303ARDZ-R7 allows for the use of smaller passive components, contributing to a compact solution. The regulator incorporates an integrated high-side MOSFET and supports current-mode control for stable line and load transient performance. Key features include precision enable with hysteresis, internal compensation, soft start, power-good output, undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD).

The device is supplied in an 8-lead SOIC package with an exposed paddle, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The ADP2303ARDZ-R7 is well-suited for intermediate power rail conversion and DC-to-DC point-of-load applications in communications, networking, industrial, instrumentation, healthcare, medical, and consumer electronics.

This regulator offers ±1.5% output accuracy over temperature. It operates as a nonsynchronous rectifier, simplifying the design for certain applications. The integrated features reduce the need for external components, streamlining the design process.
