LTM8083 36V, 1.5A Buck-Boost Module Regulator FEATURES DESCRIPTION n Complete Buck-Boost Switch Mode Power Supply The LTM 8083 is a 36V , Buck-Boost Module Regulator. IN n Wide Input Voltage Range: 3V to 36V Included in the package are the switching controller, power n Wide Output Voltage Range: 1V to 36V switches, inductor, and support components. All that is n 12V/0.8A Output at 6V needed to complete the design is resistors for setting the IN n 12V/1.5A Output at 12V output voltage and operating frequency, and input and IN n 12V/1.5A Output at 36V output capacitors. Operating over an input voltage range IN n Integrated Three-Terminal Capacitors and Spread from 3V to 36V, the LTM8083 can regulate output volt- Spectrum for Excellent EMI Performance ages between 1V and 36V with seamless low-noise tran- n Compliant with CISPR25 Class 5 Limits (Refer to sitions between operation regions, as well as controlling Figure25) both input and output average currents through external n 300kHz to 2MHz Fixed Switching Frequency with sense resistors. External Frequency Synchronization The low profile package enables utilization of unused n Adjustable Output Current Limit space on the bottom of PC boards for high density point n Output Current Monitoring of load regulation. The LTM8083 is packaged in ther- n RoHS Compliant Package mally enhanced, compact over-molded Ball Grid Array n 6.25mm 6.25mm 2.22mm BGA Package (BGA) packages suitable for automated assembly by standard surface mount equipment.
