LM20134EVAL Datasheet PDF - TI

●The LM20134EVAL evaluation board is designed to evaluate the LM20134, 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 flexibility to synchronize the switching frequency from 500kHz to 1.5MHz 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 start up response of the LM20134, and the precision enable pin can be used to easily sequence the LM20134 in applications with sequencing requirements.
