Other Description


The primary-side controller is used to simplify CV/CC mode switch design via primary voltage/ current sampling without optical and secondary-side circuit. Meanwhile, it possessed precise voltage output and current adjustment. Various mode of the chip can reach 75mW standby power consumption, high efficiency and noise immunity. Jitter Frequency also can reduce the cost of EMI filter. Also, V5370M also features to adjust CV/CC accurately, low-cost and high reliability; meanwhile, it provides various of protective function: peak-current limited in cycle, VCC under-voltage locked (UVLO), over-voltage protection (OVP), and clamp. When abnormal events happened, controller continue soft-start until the error been solved. Support DIP-7 tube package. Embedded MOSFET endurance up to 1000V to ensure reliable power supply even under the extreme environment.
