Texas Instruments LM20134EVAL

The LM20134 is a full featured buck switching regulator capable of driving up to 4A of load current. This device features a clock synchronization input that allows the switching frequency to be synchronized to an external clock source. The flexibilty to synchronize the switching frequency from 500 kHz to 1.5 MHz allows the size of the power stage components to be reduced while still allowing for high efficiency. The LM20134 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 LM20134, and the precision enable pin can be used to easily sequence the LM20134 in applications with sequencing requirements. The LM20134 is available in an eTSSOP-16 package with an exposed pad for enhanced thermal performance.
