Product Details

Evaluation circuit EVAL-ADPL74101-AZ, features the ADPL74101, a 100V step-down synchronous controller. The ADPL74101 features low IQ, up to 1MHz programmable/synchronizable switching frequency, spread spectrum, and a small 28-lead (4mm x 5mm) QFN package. These features allow for a wide variety of applications, including industrial, military, medical, and telecommunications systems.

The EVAL-ADPL74101-AZ operates from a 16V to 72V input voltage range and generates a 12V, 15A output. The ADPL74101 has a precision voltage reference that can generate an output voltage with less than 2% tolerance over the full operating conditions. The EVAL-ADPL74101-AZ is set to a 300kHz switching frequency, which results in a small and efficient circuit. The converter achieves over 94% efficiency with a 15A load at full operating V_IN, with a peak efficiency of over 96%.

This board can be easily modified to regulate output voltages from 0.8V to 60V. The evaluation circuit has been specifically designed with 100V field-effect transistors (FETs); various FETs with similar footprints can be replaced to fit a wide array of applications.

The EVAL-ADPL74101-AZ provides a high-performance, cost-effective solution for generating a 12V output. The ADPL74101 data sheet provides a complete description of this device, including its operation and application information. The data sheet must be read in conjunction with this user guide for EVAL-ADPL74101-AZ.
