CBM2596XX-3.3,5V,12,ADJ中文资料电源管理数据手册COREBAI规格书

描述 Description

The CBM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V and an adjustable output version.

Requiring a minimum number of external components, these regulators are simple to use.

The CBM2596 series operates at a switching frequency of 150kHz. Available in standard 5-lead TO-220 package.

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 100μA standby current. Self protection features include a two stage frequency reducing current limit for output switch and an over temperature shutdown for complete protection under fault conditions. The over temperature shutdown level is about 145℃ with 5℃ hysteresis.
