VPS2105
VPS2105 is a highly integrated switch mode power supply controller suitable for various flyback/buck/boost topologies. In isolated flyback power supply applications, the primary side voltage feedback PSR is used. 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 VPS2105 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 ESOP8 packaging can minimize the temperature rise of the product.
