LM25190-Q1 CCCV Buck Controller Evaluation Module
Description
The LM25190QEVM-2100
is a synchronous buck DC/DC regulator with constant-
current constant-voltage (CCCV) regulation. The EVM
operates over a wide input voltage range of 5.5V to
42V (at J1 VIN terminal), providing a regulated current
of 5A in CC mode and a regulated voltage of 5V
in CV mode. The regulation target of the average
inductor current is programmed by ISET and the
output voltage is adjusted by modifying the feedback
resistors.
Features
• Wide input voltage operating range
– 5.5V to 42V: VIN terminal
• 5V output as a default. The EVM provides
footprints for fixed 12V, 5V, or adjustable output
voltage.
• Adjustable average inductor current using ISET
• Inductor current monitor using IMON
• Integrated standard MOSFET gate drivers
