The TPS92551EVM/NOPB is an evaluation board for TPS92551, a constant current buck LED driver micro module drives maximum 450mA LED current up to 16 LEDs in a single string. It integrates all the power components including the power inductor. The TPS92551 provides a full turn key , highly efficient solution for wide range of single string LED lighting applications with up to 95% power efficiency. The module has fast control loop to realize fine LED current pulse yielding 256 step PWM dimming resolution at 240Hz for general lighting. Protection features include thermal shutdown, input under voltage lockout, LED open circuit and short circuit protections. The TPS92551 micro module is available in TO PMOD 7pin power package.

• Input voltage ranging from 4.5V to 60V
• The LED current is adjustable from 300mA to 450mA
• Constant switching frequency 800KHz
• High contrast ratio (minimum dimming current pulse width < 16μs)
• TPS92551 modules can be connected in parallel for higher current operation
• Compatible with ceramic and low ESR capacitors
• ±3.5% typical LED current accuracy
