Linear Technology LTC3404EMS8#PBF

Description
The LTC3404 is a high-efficiency monolithic synchronous step-down regulator using a constant frequency, current mode architecture. It features:
High efficiency: Up to 95%
Very low quiescent current: Only 10μA during operation
600mA output current at VIN = 3.3V
2.65V to 6V input voltage range
1.4MHz constant frequency operation
No Schottky diode required
Low dropout operation: 100% duty cycle
Synchronizable from 1MHz to 1.7MHz
Selectable Burst Mode® operation or pulse skipping mode
0.8V reference allows low output voltages
Shutdown mode draws <1μA supply current
±2% output voltage accuracy
Current mode control for excellent line and load transient response
Overcurrent and overtemperature protected
Available in 8-lead MSOP package
