onsemi CAT3604V
The CAT3604V is a high efficiency fractional charge pump that can drive up to four LEDs with input supply voltages as low as 2.5 V. Each operating mode uses a constant high frequency switching scheme which allows the use of small form factor external ceramic capacitors while delivering excellent low noise input supply ripple up to 5.5 V. The EN input control supports direct PWM dimming and can accommodate dimming frequencies in excess of 10 kHz thereby providing extremely high resolution brightness levels.| Part No. | CAT3604V |
