TS19371 - Boost (Step-up) WLED Driver

Taiwan Semiconductor Company

General Description

The TS19371 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current.

The device can drive up to 126 LEDs (9S14P) from a 12V supply.

The output capacitor can be as small as 4.7µF, saving space versus alternative solutions.

Key Features

Inherently Matched LED Current.
High Efficiency: 89% Typical.
Drives Up to 9.

TS19371 Boost (Step-up) WLED Driver with OVP SOT-26 Pin Definition: 1. SW 6. VIN 2. GND 5. OVP 3. FB 4. CTRL SOP-8 Pin Definition: 1. VIN 8. SW 2. GND 7. GND 3. GND 6. GND 4. CTRL 5. FB General Description The TS19371 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current. The device can drive up to 126 LEDs (9S14P) from a 12V supply. The output capacitor can be as small as 4.7µF, saving space versus alternative solutions. A low 95mV feedback voltage minimizes power loss for better efficiency. Additional feature include over output voltage limiting (SOT-26 package) when LEDs are disconnected. The TS19371 switches at a fixed frequency of 1.
