Synchronous Step-Down Regulator
The LTC3416 is a 95% efficient synchronous buck regulator that uses a constant frequency, current-mode architecture. It also offers voltage tracking for easy supply sequencing, and delivers up to 4 A of continuous output current at voltages as low as 0.8 V from a thermally enhanced TSSOP-20 package. Operating from an input voltage of 2.25 V to 5.5 V, it's suitable for both single-cell Li-Ion or NiMH applications, as well as more general-purpose fixed-rail systems.

The new NTD4N60, NTP6N60 and NTP10N60 high-voltage MOSFETs offer high current ratings of up to 10 A and RDS(on) as low as 0.75 μ at 10 V. They employ planar TMOS7HV technology, allowing operation in the most demanding application. Very low gate charge reduces driver loss, enabling higher efficiency than conventional technologies.

DC-DC Converter Modules
These 25-A/20-A isolated eighth-brick dc-dc converters are set to accelerate design migration from standard quarter-brick form factors. Known as “value” models, they are for applications where cost sensitivity has precluded use of the latest-generation small form factor power converter technology. They offer a choice of 1.2-V, 1.5-V, 1.8-V, 2.5-V and 3.3-V outputs.
