6A, Synchronous Buck Regulator with Input Synchronization Evaluation Module



Texas Instruments  LM20136MHEVAL

The LM20136 is a full-featured synchronous buck switching regulator capable of driving up to 6A of load current. This device features a clock synchronization input that allows the switching frequency to be synchronized to an external clock source. The ability to adjust the operating frequency from 500 kHz to 1.5 MHz gives the designer flexibility in component selection. The LM20136 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 LM20136, and the precision enable pin can be used to easily sequence the LM20136 in sequence-critical applications. The LM20136 is available in an eTSSOP-16 package with an exposed pad for enhanced thermal performance.
