The TPS92515AHVQDGQRQ1 is a compact monolithic switching regulator containing a low resistance N-channel MOSFET. This device is suitable for high brightness LED lighting applications where efficiency, high bandwidth, PWM or analog dimming, and small size are required.

TPS92515AHVQDGQRQ1 This regulator features constant off-time and peak current control. The principle of operation is quite simple: after an off-time based on the output voltage, the on-time starts. The on-time ends immediately after the inductor peak current threshold is reached. The TPS92515AHV-Q1 device can be configured to maintain constant peak-to-peak ripple during the on and off times of the shunt FET dimming cycle. This period is ideal for maintaining a linear response over the entire shunt FET dimming range.

The TPS92515AHVQDGQRQ1 high-side comparator with low offset voltage helps achieve steady-state accuracy. The LED current can be modulated using analog or PWM dimming techniques alone or in combination. Other features include undervoltage lockout (UVLO), wide input voltage operation, inherent open-LED operation, and thermal shutdown with a wide operating temperature range.
