R1260S-Y Series 60V Input / 80V Absolute Maximum Rating Synchronous Step-down DC/DC Controller for Industrial Applications
■The R1260S is a step-down DG/DC controller which can generate an output voltage of 1.0 V to 16.0 V by driving external high- / low-side NMOSFETs. By the adoption of a unique current mode PWM architecture without an external current sense resistor, this device can make up a stable DC/DC converter with high-efficiency even if adding low Ron MOSFETs and a low DCR inductor externally.
■This is a high-reliability semiconductor device for industrial application (-Y) that has passed both the screening at high temperature and the reliability test with extended hours.
●KEY BENEFITS:
■48 V power can be provided by a wide-ranging input voltage of 5 V to 60 V.
■High-accuracy feedback voltage: 0.8 V ±1.5% (-40℃ s Ta s 125℃)
■High efficiency at light load (l-OUT=1mA) by VFM control (80% @V-IN=24V, 70% @V-IN=48V)
