Product Description
STMicroelectronics STEVAL-ISA207V1 is a 3 A Step Down DC/DC Switching Regulator Evaluation Board designed for automotive system battery-powered applications. It uses the A7987 switching regulator in an HTSSOP16 package delivering reliable power management with output voltage adjustable from 0.8 V.
The board facilitates almost low drop-out operation due to its advanced integrated switch management, enhancing efficiency in power conversion. The embedded high-side power MOSFET enables current delivery up to 3 A depending on application demands.
The integrated switchover feature on the VBIAS pin and light load management with pulse skipping optimize power efficiency across varying load ranges. Additionally, the soft-start current limit and switching frequency can be tailored to specific applications, improving performance and protection.
This evaluation board includes an internal 250 kHz oscillator frequency which can be adjusted up to 1.5 MHz by selecting an appropriate resistor value. Moreover, the design allows synchronization of two A7987 regulators in a 180° out-of-phase configuration, minimizing input RMS current and electrical noise.
Manufactured in Italy, the STEVAL-ISA207V1 board meets the quality needs of automotive and industrial environments requiring robust and efficient DC/DC power regulation. The board features the A7987 switching regulator in an HTSSOP16 package.
