The LM20145 is a full featured buck switching regulator capable of driving up to 5A of load current. The switching frequency of the LM20145 can be varied from 250kHz to 750kHz with an external resistor allowing the size of the power stage components to be reduced while still providing efficient operation. The LM20145 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 LM20145, and the precision enable pin can be used to easily sequence the LM20145 in applications with sequencing requirements. The LM20145 is available in an eTSSOP-16 package with an exposed pad for enhanced thermal performance.
