This total power solution allows as few as five external components and eliminates • Supplies up to 2-A of Output Current the loop compensation and magnetics part selection • 45-V Surge Capability process. • Synchronizes to an External Clock The 9x11x2.8 mm QFN package is easy to solder • Adjustable Slow-Start onto a printed circuit board and allows a compact • Programmable Undervoltage Lockout (UVLO) design with fewer components and excellent power dissipation capability. The TPS84259 offers the • Output Overcurrent Protection flexibility and the feature-set of a discrete design and • Over Temperature Protection is ideal for powering a wide range of ICs and analog • Operating Temperature Range: –40°C to 85°C circuits requiring a negative output voltage. Advanced packaging technology affords a robust and reliable • Enhanced Thermal Performance: 14°C/W power solution compatible with standard QFN • Meets EN55022 Class B Emissions mounting and testing techniques. • For Design Help visit http://www.ti.com/TPS84259 SIMPLIFIED APPLICATION APPLICATIONS • Industrial and Motor Controls • Automated Test Equipment • Bipolar Amplifiers in Audio/Video • High Density Power Systems Safe Operating Current This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. PRODUCTION DATA information is current as of publication date. Copyright © 2012, Texas Instruments Incorporated Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. |
