IT76630M

M3TEK IT76630M 23V/3A High Efficiency Synchronous Rectified Step-Down DC/DC Converter DESCRIPTION The IT76630M is a high efficiency synchronous step-down DC/DC converter series with 3A continuous output current supplied. Included on the substrate with the features listed is a high performance trans-conductance error amplifier that provides tight voltage regulation and accuracy under transient conditions. A built-in Under Voltage Lockout (UVLO) circuit is provided to prevent start-up until the input voltage reaches to 4.5V. In addition, it features over-current protection and thermal shutdown. To improve the light load efficiency, it is designed as the power saving mode (PSM) to minimize the switching loss by reducing the switching frequency. The IT76630M is available in SOP8_EP package. FEATURES Input Voltage Supply Range from 4.5V to 23V Power Saving Mode (PSM) during the light Load Operation High Efficiency up to 93% Adjustable Output Voltage from 0.925V to 15V 3A Continuous Output Current 330KHz Constant Frequency Operation Current Mode Operation Programmable Soft-Start Over-temperature Protection Over-current Protection Input Under Voltage Lockout (UVLO) 10μA Shutdown Current SOP8_EP Package RoHS Compliant (100% Green Available) APPLICATIONS Data comm. xDSL CPE Graphics Cards Set-Top-Box, DVD Servers/Networking DSP and FPGA Power Supply Telecomm Equipments DC-DC Regulator Modules LCD Monitor and LCD TV TYPICAL APPLICATION Rev. 0.2 www.m3tekic.com Figure 1.
