DESCRIPTION
The TH1200F is a high efficiency step-down converter
optimized to drive high current LEDs. A patented
switching control algorithm allows highly efficient and
accurate LED current regulation. A single RSET
resistor sets the full scale LED string current up to
350mA from supplies as high as 36V.
The switching architecture of the TH1200F results in
extremely low internal power dissipation allowing the
device to be housed in a tiny package without the
need for dedicated heat sinking. The device is
compatible with switching frequencies of up to 1MHz,
making it ideal for applications requiring small footprint
and low value external inductors.
Analog dimming and LED shutdown control is
provided via a single input pin, CTRL. Additional
features include overload current protection and
thermal shutdown. The device is available in the low
profile 5-lead thin SOT23 package and is ideal for
space constrained applications.
