TOP244PN 16 W 85 - 265 VAC 13.55 V at 25 C Flyback Design Highlights * Lowest cost and low component count solution * Universal input voltage replaces the need for multiple linear based designs * High efficiency: >75% * Integrated line undervoltage detection (UV) and overvoltage (OV) power system surge protection * Constant voltage / constant current (CV/CC) output * Temperature compensated output voltage * Monitor input to allow state of charge measurements Operation The circuit shown in Figure 1 provides a CV/CC output for charging lead-acid batteries in applications such as fire/burglar alarms and emergency lighting. The design utilizes many of the features of the TOPSwitch-GX family. Line undervoltage and overvoltage (100 V and 450 V, respectively) are implemented using a single resistor (R13). Line undervoltage detection eliminates power-up/down output glitches, while overvoltage shutdown provides protection for short line transients and longer duration power system surges, removing the need
TOP244PN 13 W cont, 17 W pk 85 - 265 VAC 3.3 V, 5 V, 12 V, -12 V Flyback Design Highlights * High efficiency multi-ouptut flyback (77% minimum) * Topology scalable to higher powers * Excellent cross-regulation * Excellent input no-load consumption <70 mW input * 132 kHz switching frequency allows smaller transformer * Frequency jitter eliminates common-mode EMI choke * >10 dB margin against CISPR22-B conducted EMI with artificial hand grounding Operation The TOPSwitch-GX uses current mode feedback to achieve excellent no-load standby. Components C16, R1 and Q2 provide a constant current powering the TOPSwitch-GX CONTROL pin. Resistor R2 feeds the remainder of Q2 current to the M pin, reducing TOPSwitch-GX current limit with increased current. Resistor R11 sets the maximum current limit of the device. Components R6, Q1 and C13 implement slope compensation. The supply operates at full frequency at high and medium power and reduces frequency at light loads. Components D9 and C10 rectify and filter t
