Texas Instruments LM20143EVAL 仪器仪表
TEXAS INSTRUMENTS LM20143EVAL Evaluation Board, 3A, PowerWise® Adjustable Frequency Synchronous Buck Regulator
TEXAS INSTRUMENTS
The LM20143EVAL evaluation board is designed to evaluate the LM20143, a full featured buck switching regulator capable of driving up to 3A of load current. The switching frequency of the LM20143 can be varied from 500kHz to 1.5Mhz with an external resistor allowing the size of the power stage components to be reduced while still providing efficient operation. The LM20143 is capable of converting an input voltage between 2.95V and 5.5V down to an output voltage as low as 0.8V. Fault protection features include cycle by cycle current limit, output power good, and output over voltage protection. The dual function soft start/tracking pin can be used to control the start up response of the LM20143, and the precision enable pin can be used to easily sequence the LM20143 in applications with sequencing requirements. The LM20143 is available in an eTSSOP16 package with an exposed pad for enhanced thermal performance. Input voltage range of 2.95V to 5.5V Accurate current limit minimizes inductor size 97% peak efficiency Adjustable output voltage down to 0.8V Adjustable switching frequency (500kHz to 1.5MHz) 32mΩ integrated FET switches Starts into pre biased loads Output voltage tracking Peak current mode control Adjustable soft start with external capacitor Silicon Manufacturer: National Semiconductor Silicon Core Number: LM20143 Kit Application Type: Power Management - Voltage Regulator Application Sub Type: Buck Regulator Kit Contents: Evaluation Board LM20143, Datasheet, Application Notes Product Range: - Automotive Qualifications Standard: - Features: Designed to Balance Overall Solution Size with the Efficiency of the Regulator SVHC: No SVHC (15-Jun-2015) Find similar products grouped by common attribute
