DC/DC Converters
TSN-1 Series, -1 A Switching Regulator
Features
◆ Non-isolated converter for negative output
◆ Small size and low profile
◆ Pin compatible with LM79xx linear regulators
◆ No heatsink required
◆ High efficiency up to 96%
◆ Operation temp. range –40°C to +85°C
◆ Protection against overload, short circuit
and over-temperature
◆ Fixed switching frequency
◆ Wide input range up to -32 VDC
◆ Excellent line / load regulation
◆ Low standby current
◆ 3-year product warranty
The new TSN-1 series step-down switching regulators are drop-in replacement for
inefficient 79xx linear regulators. A high efficiency up to 96 % allows full load op-
eration up to +70°C (+85°C with derating) ambient temperature without the need of
any heat-sink or forced air cooling.
The TSN-1 switching regulators provide other significant features over linear regu-
lators, i.e. better output accuracy (±2 %), lower standby current of ~2 mA and no
requirement of external capacitors. They are suitable for negative output circuits.
The high efficiency and low standby power consumption make these regulators an
ideal solution for energy sensitive applications.
