LV5768V

Ordering number : ENA2093B LV5768V Bi-CMOS IC 1-channel Step-down Switching Regulator http://onsemi.com Overview The LV5768V is a 1-channel step-down switching regulator. Function 1 channel step-down switching regulator controller. Frequency decrease function at pendent. Load-independent soft start circuit. ON/OFF function. Built-in pulse-by-pulse OCP circuit. It is detected by using ON resistance of an external MOS. Synchronous rectification Current mode control SSOP16(225mil) Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Supply voltage VIN, SW HDRV, CBOOT VIN max LDRV Between CBOOT to SW Between CBOOT to HDRV Conditions Ratings Unit 45 V 45 V 52 V 6.0 V 6.0 V Allowable pin voltage EN, ILIM Between VIN to ILIM VDD SS, FB, COMP,RT Allowable Power dissipation Pd max Mounted on a specified board. *1 VIN+0.3 1.0 6.0 VDD+0.3 0.74 V V V V W Operating temperature Topr -40 to +85 °C Storage temperature Tstg -55 to +150 °C *1 Specified board : 114.3mm × 76.1mm × 1.6mm, glass epoxy board. Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.
