Typical Application for AP3156 High-Efficiency 1x/1.5x/2x Charge Pump for White LED Applications
Reka bentuk rujukan oleh: Diodes Incorporated
Typical Application for the AP3156 is a low noise, constant frequency charge pump DC/DC converter that uses a tri-mode load switch (1x), fractional (1.5x) and doubling (2x) conversion to maximize efficiency for white LED applications. The AP3156 is capable of driving the LED channels at 120mA maximum from a 2.7V to 5.5V input. The current sinks may be operated individually or in parallel for driving higher-current LEDs
