TS19370
Boost (Step-up) WLED Driver with OVP
1/8
Version: D08
SOT-26
General Description
The TS19370 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current. The
device can drive 2 ~ 9 LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED
currents resulting in uniform brightness and eliminating the need for ballast resistors. The output capacitor can be
as small as 0.22µF, saving space versus alternative solutions. A low 95mV feedback voltage minimizes power
loss for better efficiency. Additional feature include over output voltage limiting when LEDs are disconnected.
The TS19370 switches at a fixed frequency of 1.2MHz, allowing the use of tiny, low profile inductors and
capacitors to minimize footprint and cost in space consideration applications for cellular phone backlighting or
other hand held equipment.
