Product Summary

The LTC3772ETS8 is a constant frequency current mode step-down DC/DC controller in a low profile 8-lead SOT-23 (ThinSOTTM) and a 3mm × 2mm DFN package. The No RSENSE TM architecture eliminates the need for a current sense resistor, improving efficiency and saving board space. Applications are (1)1- or 2-Cell Li-Ion Battery-Powered Applications; (2)Wireless Devices; (3)Portable Computers; (4)Distributed Power Systems.

Parametrics

LTC3772ETS8 absolute maximum ratings: (1)Input Supply Voltage (VIN): –0.3V to 10V; (2)IPRG, PGATE Voltages: – 0.3V to (VIN + 0.3V); (3)VFB, ITH/RUN Voltages: – 0.3V to 2.4V; (4)SW Voltage: – 2V to (VIN + 1V)or 10V Maximum; (5)PGATE Peak Output Current (<10μs): 1A; (6)Operating Temperature Range (Note 2): – 40°C to 85°C; (7)Junction Temperature (Note 3): 125°C; (8)Storage Temperature Range: –65°C to 125°C; (9)Lead Temperature (Soldering, 10 sec)TSOT-23: 300°C.

Features

LTC3772ETS8 features: (1)No Current Sense Resistor Required; (2)40μA No-Load Quiescent Current; (3)High Output Currents Easily Achieved; (4)Internal Soft-Start Ramps VOUT; (5)Wide VIN Range: 2.75V to 9.8V; (6)Low Dropout: 100% Duty Cycle; (7)Constant Frequency 550kHz Operation; (8)Low Ripple Burst Mode Operation at Light Load; (9)Output Voltage as Low as 0.8V; (10)±1.5% Voltage Reference Accuracy; (11)Current Mode Operation for Excellent Line and Load Transient Response; (12)Only 8μA Supply Current in Shutdown; (13)Low Profile 8-Lead SOT-23 (1mm)and (3mm × 2mm)DFN (0.75mm)Packages.
