LT1072HVCK

The LT1072HVCK is designed as a monolithic high power switching regulator. It can be operated in all standard switching configurations including buck, boost, flyback, forward, inverting and cuk. A high current, high efficiency switch is included on the die along with all oscillator, control, and protection circuitry.

LT1072HVCK has ten features. (1)Available in miniDIP, TO-220 and TO-3 packages. (2)Wide input voltage range 3V to 60V. (3)Low quiescent current 6mA. (4)Internal 1.25A switch. (5)Very few external parts required. (6)Self-protected against overloads. (7)Shutdown mode draws only 50uA supply current. (8)Flyback-regulated mode has fully floating outputs. (9)Operates in nearly all switching topologies. (10)Can be externally synchronized. Those are all the main features.

Some absolute maximum ratings of LT1072HVCK have been concluded into several points as follow. (1)Its supply voltage would be 60V. (2)Its switch output voltage would be 75V. (3)Its feedback pin voltage (transient 1ms) would be +/-15V. (4)Its operating junction temperature range would be from 0°C to 100°C. (5)Its storage temperature range would be from -65°C to 150°C. (6)Its lead temperature soldering 10 seconds would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of LT1072HVCK are concluded as follow. (1)Its reference voltage would be min 1.224V and typ 1.244V and max 1.264V. (2)Its feedback input current would be typ 350nA and max 750nA. (3)Its error amplifier transconductance would be min 3000umho and typ 4400umho and max 6000umho. (4)Its error amplifier clamp voltage would be min 1.8V and max 2.3V. (5)Its reference voltage line regulation would be max 0.03%/V. (6)Its minimum input voltage would be typ 2.6V and max 3.0V. (7)Its supply current would be typ 6mA and max 9mA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
