PMIC - AC DC Converters, Offline Switchers
The TOP243GN is a low-cost, versatile off-line switcher that can incorporate into a variety of applications. It can be used to generate both AC and DC power with adjustable output voltage and power ratings over an extended input voltage range. This makes it particularly suitable for applications ranging from home appliances to industrial equipment.
The TOP243GN pre-regulator incorporates a 700 V peak, MOSFET based power stage and has a built-in current-mode PWM controller for improved line and load regulation. When powered up, the PWM controller automatically initiates the soft-start cycle and regulates the output voltage to a programmed level. It minimizes the audible noise, reduces voltage spikes and ensures stability. The TOP243GN includes an adjustable-current control and an internal soft-start for smooth turn-on emission.
The TOP243GN allows high power efficiency through a modulated light-load operation. The modulated current sliding-mode control feature minimizes the power dissipation in light-load applications, increasing the system power efficiency. The integrated Phase shift Voltage Mode control reduces EMI by eliminating high-switching frequencies while giving excellent load and line regulation.
For over-voltage or over-current protection, the TOP243GN has a protective circuit that can remove the power stage from the line when the output voltage exceeds its voltage rating. A special feature of the TOP243GN is an external detection circuit for soft-start inrush current limiting to further improve energy efficiency.
The TOP243GN has a low-side current-sensing feature that can be used to provide information about the current output load. Additionally, the TOP243GN has an integrated temperature-compensated under-voltage lockout circuit, which gives reliable and accurate results over its operating temperature range.
The TOP243GN is available in a variety of packages such as open frame and surface-mount packages. It has a wide input voltage range of 85VAC to 265VAC and is rated for operating temperature range of -45℃ to 85℃. It also features built-in frequency synchronization for better EMI at higher frequencies and low standby power consumption.
In summary, the TOP243GN is an ideal choice for any application requiring reliable, low-cost AC/DC power supply with adjustable output voltage, power ratings, over-current and over-voltage protection, and temperature compensated under-voltage lockout. Its low-cost and powerful features make it suitable for applications ranging from home electronics to industrial equipment.
