TOP258PN AC to DC offline Switching Converter IC
TOP258PN AC to DC Off-Line PWM Switch IC used in SMPS & Adapter
TOP258PN IC is a TOPSwitch-HX series which is cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
TOP258PN AC-DC offline Switcher IC is an integrated switched mode power supply chip that converts a current at the control input to a duty cycle at the open drain output of a high voltage power MOSFET. During normal operation the duty cycle of the power MOSFET decreases linearly with increasing CONTROL.
In addition to the three terminal TOPSwitch features, such as the high voltage start-up, the cycle-by-cycle current limiting, loop compensation circuitry, auto-restart and thermal shutdown, the TOPSwitch-HX incorporates many additional functions that reduce system cost, increase power supply performance and design flexibility. A patented high voltage
CMOS technology allows both the high-voltage power MOSFET and all the low voltage control circuitry to be cost effectively integrated onto a single monolithic chip.
DNA Solutions deals in retail and bulk quantity. We have various values of AC/DC Switching converter IC's. Check our complete collection of AC DC converter and offline Switcher IC's.

Features of TOP258PN 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 TOP258PN AC-DC Offline Switcher IC
- Appliances and timers
- LED drivers and industrial controls
