Description
General part information
TPS92550 Series
The TPS92550 Constant Current Buck LED Driver Micro-Module drives maximum 450mA LED current up to 10 LEDs in a single string (maximum 14W). It integrates all the power components including the power inductor. The TPS92550 provides a full turn-key, highly efficient solution for wide range of single string LED lighting applications with up to 96% power efficiency. It accepts an input voltage ranging from 4.5V to 36V and delivers a 350mA LED current as default. The LED current is adjustable from 300mA to 450mA by changing a single external resistor.
The module operates at constant switching frequency (400kHz) with low Electro Magnetic Interference (EMI) complying with EN55015 standard. The module has fast control loop to realize fine LED current pulse yielding 256–step PWM dimming resolution at 240Hz for general lighting. Protection feature include thermal shutdown, input under-voltage lockout, LED open-circuit and short-circuit protections. The TPS92550 Micro-Module is available in 7-pin PFM power package.
