Микросхемы и комплектующие STEVAL-ISA206V1

EVAL BOARD , SYNC BUCK REGULATOR

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 which along with its wide input operating voltage range, render the L6986H the ideal choice for 12V - 24V industrial standard bus. Synchronous rectification helps to achieve higher efficiency at full load as well as application compactness, while high-frequency switching (programmable up to 2MHz) helps to cut on power passive costs 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. A low noise mode (LNM) is also available to meet the requirements of infotainment applications of forced PWM mode in all loading conditions.
