Introduction
The LTC3407-3 is a dual, constant frequency, synchronous step down DC/DC converter. Intended for low power applications, it operates from 3.3V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, allowing the use of tiny, low cost capacitors and inductors with a profile ≤1.0mm. Internal synchronous 0.35Ω, 1.2A power switches provide high efficiency without the need for external Schottky diodes. A user selectable mode input is provided to allow the user to trade-off noise ripple for low power efficiency. Burst Mode operation provides high efficiency at light loads, while pulse-skipping mode provides low noise ripple at light loads.
Features
- Very Low Quiescent Current: Only 40μA at 800mA/3.3V
- High Efficiency: Up to 95%
- 2.25MHz Constant Frequency Operation
- High Switch Current: 1.2A on Each Channel
- No Schottky Diodes Required
- Low RDS(ON) Internal Switches: 0.35Ω
- VIN: 3.3V to 5.5V
- Current Mode Operation for Excellent Line and Load Transient Response
- Short-Circuit Protected
- Low Dropout Operation: 100% Duty Cycle
- Ultralow Shutdown Current: <1μA
- Power-On Reset Output
- Externally Synchronizable Oscillator
- Small Thermally Enhanced 3mm×3mm DFN Package
Applications
- PDAs/Palmtop PCs
- Digital Cameras
- Cellular Phones
- Portable Media Players
- PC Cards
- Wireless and DSL Modems
