STEVAL-ISA206V1

STEVAL-ISA206V1 is a 38V, 2A synchronous step-down switching regulator evaluation board based on L6986H. The product evaluation board is based on the L6986H synchronous step-down switching regulator that can deliver up to 2A and withstand cold cranking across 100% duty cycle. Its wide input operating voltage range renders the L6986H a choice for 12V - 24V industrial standard bus. Synchronous rectification helps achieve higher efficiency at full load and application compactness, while high-frequency switching programmable up to 2MHz helps reduce power passive cost and size while staying outside of the AM band. The device can operate in a low consumption mode (LCM) with a quiescent current down to 30µA at VIN = 12V and VOUT = 3.3V, hence assuring high efficiency at light loads, as required by typical car body applications that active during car parking.
