LTC3405AES6

LTC3405AES6 is a kind of high efficiency monolithic synchronous buck regulator. It adopts a constant frequency, current mode architecture. The typical applications include cellular telephones, personal information appliances, wireless and DSL modems, digital still cameras, MP3 players and portable instruments.

There are some features of LTC3405AES6. (1)high efficiency: up to 96%; (2)very low quiescent current: only 20A during operation; (3)300 mA output current at VIN=3V; (4)2.5 V to 5.5 V input voltage range; (5)1.5 MHz constant frequency operation; (6)no schottky diode required; (7)low dropout operation: 100% duty cycle; (8)0.8 V reference allows low output voltages; (9)shutdown mode draws < 1A supply current; (10)current mode operation for excellent line and load transient response; (11)overtemperature protected; (12)low profile (1mm) thinSOTTM package; (13)stable with ceramic capacitors;(14)±2% output voltage accuracy.
