DESCRIPTION
With a 40-V rated integrated switch FET, the

• Qualified for Automotive Applications
TPS61165-Q1 is a boost converter that drives LEDs
• 3-V to 18-V Input Voltage Range
in series. The boost converter runs at a 1.2-MHz fixed
• 38-V Open LED Protection
switching frequency with 1.2-A switch current limit,
and allows for the use of a high brightness LED in
• 200-mV Reference Voltage With 2% Accuracy
general lighting.
• 1.2-A Switch FET With 1.2-MHz Switching
The default white LED current is set with the external
Frequency
sensor resistor Rset, and the feedback voltage is
• Flexible 1 Wire Digital and PWM Brightness
regulated to 200mV, as shown in the typical
Control
application. During the operation, the LED current can
• Built-in Soft Start
be controlled using the 1 wire digital interface (
Easyscale™ protocol) through the CTRL pin.
• Up to 90% Efficiency
Alternatively, a pulse width modulation (PWM) signal
• SOT-23 Package
can be applied to the CTRL pin through which the
duty cycle determines the feedback reference
APPLICATIONS
voltage. In either digital or PWM mode, the
TPS61165-Q1 does not burst the LED current;
• High Brightness LED Lighting
therefore, it does not generate audible noises on the
• White LED Backlighting for Media Form Factor
output capacitor. For maximum protection, the device
Display
features integrated open LED protection that disables
the TPS61165-Q1 to prevent the output from
exceeding its absolute maximum voltage ratings
during open LED conditions.
The TPS61165-Q1 is available in a SOT-23 package.
