10 / 27 page Confidential MCZ5303SG, MCZ5303SH Application Manual Vol. 1.0 5RE-125294-2 – 10 – Figure 7. Connection diagram with LLC controller (MCZ5303SG) 4-8. KVc1 Terminal (pin9) The KVc1 terminal is a terminal for Vcc supply to the control IC. In burst operation, it makes the LLC perform burst operation by repeating start and stop of supply from the KVc1 terminal to reduce wasteful IC power consumption in the oscillation stop period. In burst mode (STBY: Open) COMPin terminal input threshold voltage Operation KVc1 SW Set with 1.06V Oscillation stop (KVc1 supply stop) ON --> OFF Reset with 0.96V Oscillation start (KVc1 supply start) OFF --> ON KVc1 SW: See Figure 8. 4-9. Vcc Terminal (pin12) The Vcc terminal receives a current supplied from the Vin at the time of start and from the Vw terminal after start. The UVLO threshold value of Vcc is 7V, and output of KVc1 is turned off when the value is below the threshold. For the Cvcc capacitor, select a capacity of 220uF or below with which the power supply can be started. Figure 8. Connection diagram of Vcc system (MCZ5303SG) |
