LTC3801BES6

LTC3801BES6 is a kind of constant frequency current mode step-down DC/DC controller. It is available in a low profile (1mm max) 6-lead SOT-23 (ThinSOTTM) package. It is widely used in 1- or 2-cell Li-Ion battery-powered applications, wireless devices, portable computers and distributed power systems.

There are some features of LTC3801BES6. (1)high efficiency: up to 94%; (2)high output currents easily achieved; (3)internal soft-start; (4)wide VIN range: 2.4 to 9.8 V; (5)low dropout: 100% duty cycle; (6)constant frequency 550 kHz operation; (7)burst mode operation disabled for lower output ripple at light loads; (8)output voltage as low as 0.8 V; (9)±1.5% voltage reference accuracy; (10)current mode operation for excellent line and load transient response; (11)low profile (1mm) SOT-23 package.

What comes next is the absolute maximum ratings of LTC3801BES6. (1):input supply voltage (VIN) is from -0.3 to 10 V; (2):SENSE, PGATE voltages is from -0.3 to (VIN + 0.3) V; (3):VFB, ITH/RUN voltages is from -0.3 to 2.4 V; (4):PGATE peak output current (<10s) is 1 A; (5): operating temperature range is from -40 to +85; (6):storage temperature range is from -65 to +150; (7):lead temperature (soldering, 10 seconds) is 300; (8):junction temperature is 150.
