TOPSwitch-HX
Enhanced EcoSmart®, Integrated Off-Line Switcher with Advanced Feature Set and Extended Power Range
Typical Flyback Application
Description:
TOPSwitch-HX 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.
Lower System Cost, Higher Design Flexibility
- Multi-mode operation maximizes efficiency at all loads
- New eSIP-7C and eSIP-7F packages build on PI’s experience with high power and high reliability packages
- No heatsink required up to 35 W (up to 48 W at 230 VAC) using P, G or M packages
- Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
- Line undervoltage (UV) detection prevents turn-off glitches
- Line overvoltage (OV) shutdown extends line surge limit
- Accurate programmable current limit
- Optimized line feed-forward for line ripple rejection
- 132 kHz frequency (254Y-258Y and all E packages) reduces transformer and power supply size (half frequency option for video applications)
- Tight I2f parameter tolerance reduces system cost
- Frequency jittering reduces EMI filter cost
- Heatsink is connected to SOURCE for low EMI
- Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
- Accurate hysteretic thermal shutdown function automatically recovers without requiring a reset
- Fully integrated soft-start for minimum start-up stress
- Extended creepage between DRAIN and all other pins improves field reliability
EcoSmart®– Energy Efficient
- Energy efficient over entire load range
- No-load consumption
- Less than 200 mW at 230 VAC
- Standby power for 1 W input
- >600 mW output at 110 VAC input
- >500 mW output at 265 VAC input
eSIP™ (E) Package (eSIP Package Information)
- Low junction-to-case thermal impedance (2 °C per watt)
- Low height is ideal for adapters where space is limited
- Simple clip-mounted heatsink reduces manufacturing cost

Notes:
- Minimum continuous power in a typical non-ventilated enclosed adapter measured at +50 °C ambient. Use of an external heat sink will increase power capability.
- Minimum continuous power in an open frame design at +50 °C ambient.
- Peak power capability in any design at +50 °C ambient.
- 230 VAC or 110/115 VAC with doubler.
- Packages: E: eSIP-7C, G: SMD-8C, L: eSIP-7F,
M: SDIP-10C, P: DIP-8C, Y: TO-220-7C.
