DC/DC控制器,同步 降压-升压, 2.8 V至80 V, 1输出, 400 kHz, QFN-38
The from is an 80V, VIN and VOUT synchronous 4-switch buck-boost DC to DC controller in 38 pin QFN package. It is a high performance buck-boost switching regulator controller operates from input voltages above, below or equal to the output voltage. It has integrated input current, input voltage, output current and output voltage feedback loops. With a wide 2.8V to 80V input and 1.3V to 80V output range, the LT8705A is compatible with most solar, automotive, telecom and battery-powered systems. The LT8705A is an improved pin compatible version of the LT8705 and is recommended for new designs. The device includes a MODE pin to select among burst mode operation, discontinuous or continuous conduction mode at light loads. Additional features include a 3.3V/12mA LDO, a synchronizable fixed operating frequency and onboard gate drivers. It is used in high voltage buck-boost converters and input or output current limited converters.
