TOP245PN AC to DC offline Switching Converter IC
TOP245PN AC to DC Off-Line PWM Switch IC used in SMPS & Adapter
TOP245PN IC is a TOPSwitch-GX family which uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET,PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions are integrated to reduce system cost and improve design flexibility, performance and energy efficiency.
Depending on package type, either 1 or 3 additional pins over the TOPSwitch standard DRAIN, SOURCE and CONTROL terminals allow the following functions: line sensing (OV/UV,line feed-forward/DCMAX reduction), accurate externally set current limit, remote ON/OFF, synchronization to an external lower frequency, and frequency selection (132 kHz/66 kHz).

All package types provide the following transparent features: Soft-start, 132 kHz switching frequency (automatically reduced at light load), frequency jittering for lower EMI, wider DCMAX, hysteretic thermal shutdown, and larger creepage packages. In addition in TOP245PN AC-DC offline Switcher IC all critical parameters (i.e. current limit, frequency,PWM gain) have tighter temperature and absolute tolerances to simplify design and optimize system cost.

Features of TOP245PN offline switcher IC
- Extended power range for higher power applications
- No heatsink required up to 34 W using P/G packages
- 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
- Separate line sense and current limit pins on Y/R/F packages
- Line under-voltage (UV) detection: no turn off glitches
- Line overvoltage (OV) shutdown extends line surge limit
- Line feed-forward with maximum duty cycle (DCMAX) reduction rejects line ripple and limits DCMAX at high line
- Frequency jittering reduces EMI and EMI filtering costs
- Regulates to zero load without dummy loading
- 132 kHz frequency reduces transformer/power supply size
- Half frequency option in Y/R/F packages for video applications
- Hysteretic thermal shutdown for automatic fault recovery
- Large thermal hysteresis prevents PC board overheating
Applications of TOP245PN AC-DC Offline Switcher IC
- Appliances and timers
- LED drivers and industrial controls
