Product Introduction
VPS2104/2104N is a highly integrated low-power isolated flyback power controller. The device integrates a 4V-100V startup circuit, a 120V/0.1 Ω - LDMOS, and a "lossless" peak current sampling circuit. The peak current setting can be easily achieved through an external resistor.
The maximum operating frequency of VPS2104/2104N can be programmed externally and can operate in both DCM and CCM modes. It can simulate frequency reduction under light loads to improve efficiency and reduce no-load power consumption. To improve the reliability of the power supply, the device also integrates a series of protection functions, including input undervoltage protection, output short circuit protection, output overvoltage protection, and over temperature protection. All control circuits and power MOSFETs are integrated on a single wafer, and the devices using advanced BCD semiconductor technology can withstand high temperatures up to 180 ℃. The use of enhanced heat dissipation packaging can minimize the temperature rise of the product.
