TELEFUNKEN SEMICONDUCTORS – Releases High Voltage Family of Synchronous Buck
Regulators with up to 26V Input and 93% efficiency
Heilbronn, Germany - December 15, 2010
TELEFUNKEN Semiconductors today announced the release of its
TF600X
family of high voltage DC-DC synchronous buck regulators to deliver very high efficiency
regulated outputs. The family consists of three parts
TF6001, TF6002 and TF6003
that operate from
4.5V to 26V Input and provide
1A, 2A and
3A adjustable regulated outputs. Achieving efficiencies up to 93% and
with low standby currents these products are optimized to provide the designer with
improved overall efficiencies thereby enabling systems to comply with Green Energy
Requirements in end applications.
The
TF600X family is a current mode, fixed frequency synchronous
buck regulators manufactured on a SOI (Silicon on Insulator) BCD process that offers
best in class performance and ruggedness with high reliability. The regulators operate
at 340 KHz fixed frequency and the current mode control architecture enables fast
transient response. The
high and low side MOSFETS are integrated
with Rds of
140m-Ohms for TF6001, 130m-Ohms for TF6002 and 100m-Ohms for TF6003.
The
low Rds switches help the regulators achieve a
peak efficiency
of 93%. The adaptive, non-overlapping MOSFET gate-drivers and high-side
bootstrap structure helps to further maximize efficiency. Output voltage is adjustable
down to 0.923 V with a set of external resistors with 2.5% voltage reference accuracy
over
-40°C to 85°C operating temperature range.
The TF600X family is targeted at point of load applications in consumer and computing
end products such as
Digital TV’s, Blu-Ray DVD Players, xDSL Modems,
Set Top Boxes, Notebooks and Netbooks. The products have built in soft
start, under-voltage lockout, over-current, and thermal shutdown protection to help
protect the device from damage during fault conditions. TF6001 and TF6002 are offered
in 8 pin SOIC Package and the TF6003 in 8 pin SOIC with exposed pad package for
improved thermal dissipation.
The TF6001, TF6002 and TF6003 are priced at $0.79, $0.89 & $0.99 in 1K quantities.
