3 Description
With a 40-V rated integrated switch FET, the
TPS61165 device is a boost converter that drives
LEDs in series. The boost converter runs at a
1.2-MHz fixed switching frequency with 1.2-A switch
current limit, allowing the use of a high-brightness
LED in general lighting.
The default white LED current is set with the external
sensor resistor Rset, and the feedback voltage is
regulated to 200 mV, as shown in Typical Application.
During the operation, the LED current can be
controlled using the one-wire digital interface
(EasyScale™ protocol) through the CTRL pin.
Alternatively, a pulse-width-modulation (PWM) signal
can be applied to the CTRL pin through which the
duty cycle determines the feedback reference
voltage. In either digital or PWM mode, the
TPS61165 device does not burst the LED current;
therefore, it does not generate audible noises on the
output capacitor. For maximum protection, the device
features integrated open-LED protection that disables
the TPS61165 device to prevent the output from
exceeding its absolute maximum voltage ratings
during open LED conditions.
