Looks like the Nat Semi part of TI has been busy ... they have announced so=
me synchronous buck regulators obviously aimed at use in new 48V car electr=
ic systems, but I can imagine they will find pretty wide use elsewhere.


To quote ...

Designing power solutions for high-voltage systems presents challenges with=
 board space, thermal performance, and total solution cost. Design time is =
critical, too, requiring solutions that are easier to use and design in. Th=
ese issues are common in applications like high-voltage industrial, automot=
ive battery management, and non-isolated and isolated telecom systems that =
require 100V transient protection.=20
To help address these challenges, Texas Instruments introduces LM5017, LM50=
18, and LM5019, the industry's first family of 100V synchronous integrated =
buck regulators providing unparalleled power density and ease of use. The L=
M5017 with integrated FETs provides 600mA of output current and operates up=
 to 100V, delivering peace of mind to designers facing high-voltage input t=
ransient conditions.	 	=20

Featured Products
 	*	LM5017 - For input voltages up to 100V, this Constant On-Time synchrono=
us buck regulator requires no loop compensation, provides excellent transie=
nt response, and enables very low step-down ratios for communications infra=
structure, automotive, and industrial applications and can also be used as =
an isolated bias supply.
 	*	LM5018 - For input voltages up to 100V with 300 mA output current.

 	*	LM5019 - For input voltages up to 100V with 100 mA output current.
