Product Description
STMicroelectronics STEVAL-ISA201V1 Evaluation Board is an advanced DC-DC converter platform based on the L5987 step-down converter IC. This evaluation board supports input voltages from 2.9 to 18 V DC and offers an adjustable output voltage starting as low as 0.6 V, with the default assembled output voltage set to 1.8 V. It is engineered for power management applications requiring efficient voltage regulation and moderate current delivery up to 3 Amps.
The switching frequency of the board can be tailored from 250 kHz up to 1 MHz, with a factory default of 430 kHz, enabling optimization between efficiency and component size. The device features zero-load current operation to minimize power wastage during standby periods and supports low dropout operation, providing a continuous 100% duty cycle when required.
Additional integrated functionalities include an internal soft-start mechanism for gradual power ramp-up, an inhibit input for easy enable/disable controls, and comprehensive protections against overcurrent and overheating conditions, thereby ensuring robust operation and longevity of connected systems.
This evaluation board is suitable for industrial, laboratory, development, and power management design applications where reliable DC-DC conversion is essential. The board facilitates rapid prototyping and performance testing of the L5987 converter chip technology.
