SMC2596A

PWM Control Step-Down DC/DC Converter SMC2596A ■DESCRIPTION 150KHz, 3A PWM Buck DC/DC Converter ■FEATURE The SMC2596A series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltage of 3.3V and 5V an adjustable Coutput version. The SMC2596A operates at a switching frequency of 150KHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 70μA(Typ.) standby current.  3.3V, 5V, and adjustable output versions  Adjustable version output voltage range 1.23V to 37V  Input voltage range up to 40V  Guaranteed 3A output current  150KHz fixed frequency internal oscillator  Built-in thermal shutdown and current limit protection  TTL shutdown capability, low power standby mode  Uses readfily available standard inductors ■APPLICATIONS  Positive to negative converter  On-Card switching regulation  Simple high efficiency Step-down regulator SMC2596A-XXD-TRG ROHS Compliant This is Halogen Free ■PIN CONFIGURATION Metal Tab GND ■PART NUMBER INFORMATION SMC 2596A- XX D TR G a b cd ef FBEN GND VOUT VIN TO263-5L Top...
