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
