It is capable of driving 3A load with excellent line and load regulations. These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version. The AMC2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It requires only a minimum number of external components. Substantially, it reduces not only the area of board size but also the size of the heat sink. In some cases, no heat sink is required. The ± 4% tolerance on output voltage within specified input voltages and output load conditions is guaranteed. The oscillator frequency accuracy is within ±10%. External shutdown is included, featuring 70 µA(typical) standby current. The output switch includes cycle-by-cycle current limitation, as well as thermal shutdown for full protection under fault conditions. Guaranteed 3A output current 3.3V, 5V and adjustable output versions Wide input voltage range, up to 40V Internal oscillator of 52 KHz fixed frequency Wide adjustable version output voltage range, from 1.23V to 37V ±4% max over line and load conditions Low standby current, typ. 70 µA, at shutdown mode Requires only 4 external components Thermal shut down and current limit protection P+ Product enhancement tested APPLICATIONS PACKAGE PIN OUT LCD Monitors ADD-ON Cards Switching Regulators High Efficiency Step-Down Regulators Efficient Pre-regulator for Linear Regulators VOLTAGE OPTIONS AMC2576-3.3 – 3.3V Fixed AMC2576-5.0 – 5.0V Fixed AMC2576-ADJ – Adjustable Output 5-Pin Plastic TO-220 (Top View) 5.
