ACT4515 provides up to 1.5A output current at 210kHz switching frequency. Active CC is a patent-pending control scheme to provide Figure 1: Schematic of Charger CC function accuracy by sensorless constant current control, which eliminates the expensive, high accuracy current sense resistor, making it ideal for battery charging applications. charging applications. The ACT4515 operates at constant output voltage mode until it reaches the CC limit set by the ISET resistor. The devices are available in a SOP-8 package. Key Component Selection Higher output inductance reduces the inductor peak -to-peak current at the expense of higher larger core size and inductance DCR value. Usually, an optimum inductance value is selected to make its peak-to-peak current 20%-30% of the maximum load current. The Schottky diode must have current rating higher than the maximum output current and the reverse voltage rating higher than the maximum input voltage. Output capacitor is selected to keep the peak-to-peak voltage ripple under required value and also meet the load transient requirements. For this application, 22uFx2 ceramic capacitors are needed. In the case of tantalum or electrolytic types, 220uF capacitor is connected in parallel with a small 1ìF-10uF ceramic capacitor to achieve small output voltage ripple and meet the requirements of input and load dynamic response.

F SW 1 0 . 9 * 0 .396 2 I OUTCC L P ( ) ( ) R CS V OUTCC 2 (1) L=51.0mm W=31.1mm H=14.2mm Lp is the transformer inductance value, Rcs is the current sense resistor, which is shown as R4 in the schematic. Fsw is the switching frequency, which design value is 45kHz. ŋ is the overall system efficiency, which value is approximately equal to 70%. Voutcc is the output voltage, which setting is through the flyback voltage of auxiliary winding and the feedback resistor R8, R9 as shown in formula (2). Operation and Application Figure 1 is the schematic of an offline charger using ACT361 to provide output power of 5V1000mA. This circuit is a typical flyback power supply which includes the AC rectified circuit (D1D4,C1, L1, L2, C2),power drive circuit (BD pin, Q1), secondary rectified circuit (D7, C6) and the IC control circuit. ACT361 is a Primary Side Regulator (PSR) so that the power supply unit can regulate current and voltage without Optocoupler. Pin 4 and Pin 2 are the VDD and ground pins to provide power for the IC. Pin 3 is the base drive for the NPN transistor. Pin 1 is the switching pin. Pin 5 is the feedback pin that senses the output current and output voltage. Pin 6 is the peak current sense pin. Resistance of R7 determines the output DC cord compensation percentage. This circuit can be used as universal charger for Cell Phones, PDAs, MP3,Portable Media Players, DSCs, and Other Portable Devices and Appliances. VOUTCC V REF (1 R8 NS ) VSEC _ R R9 N AUX (2) Np/Ns/Naux (140/10/14) must be designed correctly to ensure it operates in DCM in all conditions.
