| ANPEC：APW7207-1MHz, High-Efficiency, Step-Up Converter for 2 to 6 White LEDs |
|
The APW7207 is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 6 white LEDs in series.
The series connection allows the LED current to be identical for uniform brightness. Its low on-resistance of NFET and feedback voltage reduces power loss and achieves high efficiency. Fast 1MHz current-mode PWM operation is available for input and output capacitors and
a small inductor while minimizing ripple on the input supply. The OVP pin monitors the output voltage and stops switching if exceeds the ver-voltage threshold. An internal soft-start circuit eliminates the inrush current during start-up.
The APW7207 also integrates under-voltage lockout, over-temperature protection, and current limit circuits. The APW7207 is available in TSOT-23-6A packages.
