STMicroelectronics L7983 | Demoboard STEVAL-L7983ADJ

Description

The STEVAL-L7983ADJ step-down switching power supply evaluation board is based on the L7983PUR regulator in an DFN10 3x3 mm package with 12 V set output voltage. The selected switching frequency is 1 MHz and it can be adjusted by applying an external clock on the LNM/LCM pin or by changing the frequency programming resistor. STEVAL-L7983ADJ IMAGEThe step-down monolithic switching regulator can deliver up to 300 mA DC based on peak current mode architecture. The wide input voltage range and adjustable UVLO threshold meet the specification for 12 V, 24 V and 48 V industrial bus standards.
