LTC3408
1.5MHz, 600mA
Synchronous Step-Down
Regulator with Bypass Transistor
U FEATURES DESCRIPTIO ■ The LTC ®3408 is a high efficiency monolithic synchronous buck regulator optimized for WCDMA power amplifier applications. The output voltage can be dynamically
programmed from 0.3V to 3.5V. At VOUT > 3.6V an internal
0.08Ω bypass P-channel MOSFET connects VOUT directly
to VIN, eliminating power loss through the inductor. ■
