Switched mode power supply controller
IC from NXP for notebook/netbook adapters
NXP Semiconductor has launched the GreenChip TEA1733 (L),
a new low cost Switched Mode Power Supply (SMPS) controller
IC intended for flyback topologies. The TEA1733 (L) IC increases
energy efficiency and standby performance of power supplies
under 75W, and suitable for low-power computing and communication
applications such as netbook adapters, printer adapter and
LCD monitor supplies.
TEA1733 is the first member a complete series of low-power
AC/DC control ICs to be launched over the next year by NXP.
The key features of the TEA1733 (L) IC are,
Operating input voltage ranges from 12 V to 30 V
Typically 10-uA low supply current during start-up and restart
Low supply current during normal operation (typically 0.5
mA without load)
Overpower or high/low line compensation
Adjustable overpower time-out, overpower restart timer
Fixed switching frequency with frequency jitter to reduce
EMI
Slope compensation for CCM operation
Low and adjustable OverCurrent Protection (OCP) trip level
Adjustable soft start
Two protection inputs (e.g. for input UVP and OVP, OTP and
output OVP)
IC overtemperature protection
The GreenChip family of ICs is designed for energy saving
and has, from its inception, led PC, notebook power efficiency.
"With the demand for sleek, light and compact designs
increasing by the day, the TEA1733 enables consumers to
experience lighter and more compact netbook adapters that
save money and consume less power," said Edwin Kluter,
marketing director, power solutions, NXP Semiconductors.
"The GreenChip TEA1733 enables new levels of energy
efficiency in low-power applications. By reducing the number
of external components needed, the TEA1733 allows OEMs to
become more cost competitive while maintaining a high degree
of quality and reliability."
