General Description
The APW7136A/B/C is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 8 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 reduce power loss and achieves high efficiency.
Fast 1MHz current-mode PWM operation is available for input and output capacito...
