LM20144EVAL

TEXAS INSTRUMENTS  LM20144EVAL  评估板, LM20144 1.2V, 4A 同步降压稳压器

The LM20144 is a full featured buck switching regulator capable of driving up to 4A of load current. The switching frequency of the LM20144 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 LM20144 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 startup response of the LM20144, and the precision enable pin can be used to easily sequence the LM20144 in applications with sequencing requirements. The LM20144 is available in an eTSSOP-16 package with an exposed pad for enhanced thermal performance.
