PT2210
PT2210 is Monolithic AC-DC PWM Controller manufactured by PowTech.
DESCRIPTION
The PT2210 is a monolithic current mode PWM controller for AC-DC applications. The device integrates a power switch and controlling circuits providing low standby power and cost effective solution for the AC-DC converter applications. The PT2210 operates at fixed 65KHz. Under no load or light load conditions, switching frequency is reduced to minimize switching loss. Low standby power and high efficiency is thus achieved. The built in LEB on the current sense input removes the signal glitches due to snubber circuit diode reverse recovery and thus reduces the external ponent count and thus the system cost in the design. A plete set protection is implemented in the PT2210 including cycle-by-cycle current limiting (OCP), over load protection (OLP), VDD over voltage and under voltage lockout (UVLO). The PT2210 also features latched shut down including programmable OTP and programmable OVP protection. By limiting the...
