Conv DC-DC 2.7V to 5.5V Step Down Single-Out 3.3V 5A 24Pin LFCSP EP T/R
Product Details
The ADP2165/ADP2166 are high efficiency, current mode control, step-down dc-to-dc regulators with an integrated 19 mΩ high-side FET and a 15 mΩ synchronous rectified FET. The ADP2165/ADP2166 combine a small size, 4 mm × 4 mm LFCSP package with an accurate current limit, resulting in a smaller inductor size and a high power density, point of load solution.
Key features include precision enable, power-good monitor, and output voltage tracking to facilitate robust sequencing. The switching frequency can be programmed from 250 kHz to 1.4 MHz, or it can be fixed at 620 kHz or 1.2 MHz. The synchronization function allows the switching frequency to synchronize to an external clock, minimizing the electromagnetic interference EMI of the system.
The ADP2165/ADP2166 are designed to be extremely flexible with the addition of a minimal amount of external components to program soft start and control loop compensation.
he ADP2165/ADP2166 are supplied from an input voltage of 2.7 V to 5.5 V. Output voltage options include 3.3 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, or 1.0 V fixed outputs and adjustable options capable of supporting an output voltage range from 0.6 V to 90% of the input voltage. Protection features include undervoltage lockout UVLO, overvoltage protection OVP, overcurrent protection OCP, and thermal shutdown TSD for robust performance.
The ADP2165/ADP2166 operate over the −40°C to +125°C junction temperature range and are available in a 24-lead LFCSP package.
