The TPS61161ADRVR is a boost converter that drives LEDs in series and has a 40-V rated integrated switch FET.

TPS61161ADRVR Description

The TPS61161ADRVR is a boost converter that drives LEDs in series and has a 40-V rated integrated switch FET. To eliminate output ripple, enhance conversion efficiency, and allow for the use of small external components, the boost converter operates at a set switching frequency of 600kHz.

As demonstrated in the typical application, the default white LED current is set using the external sensor resistor Rset, and the feedback voltage is regulated to 200mV. During operation, a pulse width modulation (PWM) signal applied to the CTRL pin can regulate the LED current, with the duty cycle determining the feedback reference voltage. The TPS61161ADRVR does not burst the LED current in PWM  dimming mode, hence there are no loud noises on the output capacitor. The device has an incorporated open LED protection function that disables the TPS61161ADRVR to prevent the output from exceeding the absolute maximum ratings under open LED conditions for maximum protection.

The TPS61161ADRVR is available in a space-saving, 2mm × 2mm QFN package with a thermal pad.

TPS61161ADRVR Layout

Layout is a key design phase for all switching power supplies, especially those with high frequency and high current. If the layout isn't done correctly, the regulator may have instability as well as noise issues.

The SW pin rise and fall timings are kept as short as feasible to prevent switching losses. The right layout of the high-frequency switching path is critical for preventing the radiation of high-frequency resonance problems.

To reduce inter-plane coupling, keep any traces linked to the SW pin as short and as little as possible. Always utilize a ground plane beneath the switching regulator. The PWM  switch, Schottky diode, and output capacitor are all part of a loop that contains a lot of currents that rise and fall in nanoseconds and should be kept as brief as possible. In order to limit the IC supply ripple, the input capacitor must be close not only to the VIN pin but also to the GND pin. A sample arrangement is depicted in the accompanying figure.
