The LT8060x and LT8060xHV are a family of buck regulators featuring the Silent Switcher® architecture, which delivers high efficiency at frequencies up to 3 MHz while minimizing electromagnetic interference (SWITCHES) emissions.
The LT80602 and LT80602HV can supply a maximum continuous current of 2.5A, the LT80603 and LT80603HV up to 3.5A, and the LT80603A and LT80603AHV up to 4.5A. With a quiescent current of 8μA when the output is fully regulated, they are suitable for applications requiring maximum efficiency at light loads. The EN/UV pins allow for setting high-precision enable thresholds, and the RT pin resistor allows for programming SWITCHES frequency.
The LT8060x and LT8060xHV feature a fast top-SWITCHES minimum on-time of 25ns (typical), as confirmed in product testing, enabling high-frequency conversion from high V IN to low V OUT.
Furthermore, this device is equipped with PG/TJ pins, which can be used to monitor the output voltage and die temperature status.
Die temperature monitors allow for direct measurement of SILICONE die temperature, enabling robust and reliable POWER SUPPLIES designs.
