LTC4041IUFD#PBF Product Details

Power by Linear™ / Analog Devices' LTC4041IUFD#PBF is a complete supercapacitor backup system for 2.9 V to 5.5 V supply rails. The device contains a high current step-down DC/DC converter to charge a single supercapacitor or two supercapacitors in series. When input power is unavailable, the step-down regulator operates in reverse as a step-up regulator to back up the system output from the supercapacitor(s).The LTC4041's adjustable input current limit function reduces charge current to protect the input supply from overload while an external disconnect switch isolates the input supply during backup. When the input supply drops below the adjustable PFI threshold, the 2.5 A boost regulator delivers power from the supercapacitor to the system output.An optional input overvoltage protection (OVP) circuit protects the LTC4041IUFD#PBF from high voltage damage at the VIN pin. An internal supercapacitor balancing circuit maintains equal voltages across each supercapacitor and limits the maximum voltage of each supercapacitor to a pre-determined value. The LTC4041IUFD#PBF is ideal for power meters and industrial alarms.<strong>Features:</strong> 2.5 A step-down supercapacitor charger and 2.5 A step-up backup supply, 6.5 A switches for 2.5 A backup from one supercapacitor or two in series, Input current limit prioritizes load over charge current, Input disconnect switch isolates input during backup, Automatic seamless switch-over to backup mode, Programmable charge current and charge voltage, Input power fail indicator, System power good indicator, Optional OVP circuitry protects device to >60 V, Constant frequency operation, Internal supercapacitor balancer (no external resistors), Power meters, Industrial alarms, Ride-through "dying gasp" supplies, High current ride-through 3 V to 5 V UPS, Servers, Solid state drives
