The LTC3408 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.
The input voltage range is 2.5V to 5V making the LTC3408 ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems.
Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode.
The LTC3408 is available in a low profile (0.75mm) 8-lead 3mm × 3mm DFN package.
Applications
- WCDMA Cell Phone Power Amplifiers
- Wireless Modems
