LTC3563EDC-TRMPBF

The LTC3563EDC-TRMPBF is designed as a high efficiency monolithic synchronous buck converter using a constant frequency, current mode architecture. A voltage select input allows the user to program the output voltage to 1.28V or 1.87V. Supply current during operation is only 26A, dropping to <1A in shutdown.

The LTC3563EDC-TRMPBF has fourteen features. (1)High efficiency: up to 96%. (2)Pin selectable output voltage: 1.28V/1.87V. (3)Low ripple (<20mVP-P) burst mode at operation Iq=26A. (4)Very low quiescent current: only 26A. (5)2.5V to 5.5V input voltage range. (6)2.25MHz constant frequency operation. (7)Low dropout operation: 100% duty cycle. (8)No schottky diode required. (9)Internal soft-start limits inrush current. (10)Shutdown mode draws <1A supply current. (11)±2% output voltage accuracy. (12)Current mode operation for excellent line and load transient response. (13)Overtemperature protected. (14)Available in 2mm * 2mm 6-lead DFN. Those are all the main features.

Some absolute maximum ratings of LTC3563EDC-TRMPBF have been concluded into several points as follow. (1)Its input supply voltage would be from -0.3V to 6V. (2)Its Vout, run voltages would be from -0.3V to Vin. (3)Its Vsel voltage would be from -0.3V to Vin+0.3V. (4)Its SW voltage would be from -0.3V to Vin+0.3V. (5)Its operating ambient temperature range would be from -40°C to 85°C. (6)Its junction temperature would be 125°C. (7)Its storage temperature range would be from -65°C to 125°C. (8)Its reflow peak body temperature DFN would be 260°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 LTC3563EDC-TRMPBF are concluded as follow. (1)Its operating voltage range would be from 2.5V to 5.5V. (2)Its output voltage would be min 1.254V and typ 1.28V and max 1.306V for Vsel=0V and would be min 1.832V and typ 1.87V and max 1.908V for Vsel=high. (3)Its reference voltage line regulation would be typ 0.04%/V and max 0.2%/V. And so on. If you have any question or suggestion or want to know more information please contact us for details.
