APE1601/A

White LED Driver (120mA Charge Pump with Current Source)

Short Circuit Protection

A current limiting circuit is also included in the APE1601/A for short circuit protection.

Whenever output source a dangerously high current, the current limiting circuit takes over

the output regulation circuit and reduces the output current at an acceptable level.

Application Information

Selecting Capacitors

To get the better performance of APE1601/A, the selecting of peripherally appropriate

capacitor and value is very important. These capacitors determine some parameters such

as input and output ripple, power efficiency, maximum supply current by charge pump, and

start-up time. To reduce the input and output ripple effectively, the low ESR ceramic

capacitors are recommended. Generally, to reduce the output ripple, increasing the output

capacitance C_OUTis necessary. However, this will increase the start-up time of output

voltage. For LED driver applications, the input voltage ripple is more important than output

ripple. Input ripple is controlled by input capacitor C_IN, increasing the value of input

capacitance can further reduce the ripple. Practically, the input voltage ripple depends on

the power supply’s impedance. If a single input capacitor C_INcannot satisfy the

requirement of application, it is necessary to add a low-pass filter as shows in Figure 1.

Frgure1. C-R-C filter used to reduce input ripple

The flying capacitor C1 and C2 determine the supply current capability of the charge

pump and to influence the overall efficiency of system. The lower value will improve

efficiency, but it will limit the LED’ s current at low input voltage.
