Description
Rectifier circuits are used to convert Analog Current (AC) into Direct Current (DC). However, in power electronics applications term AC/ DC converter is used where controlled rectification is possible with filtering and regulation. AC DC converters can be designed using linear devices or by using switching devices, switching converters are more reliable, small and cheap but are more complex as compared to the converters designed using linear devices.
IC TOP247 YN integrates high power MOSFET, pulse width modulation circuit, fault protection and control circuit on single CMOS chip. In order to improve the chip performance and energy efficiency to have lower cost may new features are introduced in the TOP247 YN
Features
● Extended power range for higher power applications
● No heatsink required up to 34 W using P package
● Features eliminate or reduce cost of external components
● Fully integrated soft-start for minimum stress/overshoot
● Externally programmable accurate current limit
● Wider duty cycle for more power, smaller input capacitor
Pictorial View
It is six pin IC that is available in plastic TO-220-7C package with lead finish of pure matt tin.

Working Principle
Functional block diagram of the TOP247YN is shown in the figure below. Its consists of error amplifier, oscillator, PWM comparator, current limiting circuit, line sense unit, line under voltage detector, line over voltage protection, Hysteretic over temperature protection and soft start circuit.
These all circuits work together effectively to provide the features like soft start which limits the peak current, higher switching frequency of up to 132 KHz, hysteretic over-temperature shutdown which ensures automatic recovery after thermal faults, lower input voltage requirements and higher power capabilities
Applications
TOP247YN is a AC-DC convert and popularly used IC in its family of ICs. IC is used in the following applications
● Universal Power supply
● Process control power supply
● LED drives
● Flyback Circuits
Flyback Converter
Flyback converters are used in AC/DC and DC/DC conversion. Flyback converter is a buck boost converter with inductor split to form a transformer, so that voltage ratios are multiplied with additional advantage of isolation. While circuit is turned ON energy is transformer from input source to the transformer at the same time capacitor that is connected at the output supplies energy to the load. While in OFF state energy is transferred to from the transformer to the output capacitor and the load. By controlling the duty cycle DC output between zero to a maximum design limit can be achieved. Diagram of Flyback converter using TOP247YN is shown in the figure below.
Power Factor Corrected LED drive
A power supply for LED drive applications is shown in the figure below. AC input to the circuit can be anywhere between 85 to 277V, and output form the circuit is 12V with a maximum current of 1.67A.
