產品信息

XZ4201 is a highly integrated current mode PWM controller.providing low standby power and cost effective system solution for the sub 30W flyback
converter applICations. PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load
condition, the IC enters ‘Green Mode’ operation to minimize switching loss and low standby power and high efficiency is thus achieved. XZ4201 also features low VDD startup current which also contributes to low standby power. The built in LEB on the current sense
input removes the signal glitch due to snubber circuit diode reverse recovery and will greatly reduce the external component count and system cost in the design.Rich protection is implemented in XZ4201 including cycle-by-cycle current limiting (OCP), over load protection (OLP), VDD over voltage clamp and under voltage lockout (UVLO). Gate drive output is clamped at 18V to protect the power MOSFET. By limiting the minimum frequency above 22 kHz eliminates the potential audible noise when the system works under light or no load conditions. Excellent EMI performance is achieved with
C.R.PowTech proprietary frequency Jittering technique together with soft driving control at totem pole gate
drive output.The XZ4201 is available in SOT23-6, SOP-8 and DIP-8 packages.
