TOP252-262 TOPSwitch-HX Family Enhanced EcoSmart, Integrated Off-Line Switcher with Advanced Feature Set and Extended Power Range Product Highlights Lower System Cost, Higher Design Flexibility • Multi-mode operation maximizes efficiency at all loads • New eSIP-7F and eSIP-7C packages • Low thermal impedance junction-to-case (2 °C per watt) • Low height is ideal for adapters where space is limited • Simple mounting using a clip to aid low cost manufacturing • Horizontal eSIP-7F package ideal for ultra low height adapter and monitor applications • Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink • No heat sink required up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC • Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset • Allows both primary and secondary sensing • 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/L packages) reduces transformer and power supply size • Half frequency option for video applications • Frequency jittering reduces EMI filter cost + AC DC IN OUT - D TOPSwitch-HX V CONTROL C S XF Figure 1. Typical Flyback Application. PI-4510-100206 • Heat sink 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 Output Power Table Product5 230 VAC ±15%4 Adapter1 Open Frame2 Peak3 TOP252PN/GN 9W TOP252MN 15 W 21 W 21 W 85-265 VAC Adapter1 Open Frame2 6W 10 W Peak3 13 W 13 W TOP253PN/GN TOP253MN 15 W 38 W 25 W 9W 43 W 15 W 25 W 29 W TOP254PN/GN TOP254MN 16 W 28 W 47 W 62 W 11 W 20 W 30 W 40 W TOP255PN/GN TOP255MN 19 W 30 W 54 W 81 W 13 W 22 W 35 W 52 W TOP256PN/GN TOP256MN 21 W 34 W 63 W 98 W 15 W 26 W 40 W 64 W TOP257PN/GN TOP257MN 25 W 41 W 70 W 119 W 19 W 30 W 45 W 78 W TOP258PN/GN TOP258MN 29 W 48 W 77 W 140 W 22 W 35 W 50 W 92 W Product5 TOP252EN/EG 230 VAC ±15% Adapter1 Open Frame2 10 W 21 W 85-265 VAC Adapter1 Open Frame2 6 W 13 W TOP253EN/EG 21 W 43 W 13 W 29 W TOP254EN/YN/EG 30 W 62 W 20 W 43 W TOP255EN/YN/EG 40 W 81 W 26 W 57 W TOP255LN 40 W 81 W 26 W 57 W TOP256EN/YN/EG 60 W 119 W 40 W 86 W TOP256LN 60 W 88 W 40 W 64 W TOP257EN/YN/EG 85 W 157 W 55 W 119 W TOP257LN 85 W 105 W 55 W 78 W TOP258EN/YN/EG 105 W 195 W 70 W 148 W TOP258LN 105 W 122 W 70 W 92 W TOP259EN/YN/EG 128 W 238 W 80 W 171 W TOP259LN 128 W 162 W 80 W 120 W TOP260EN/YN/EG 147 W 275 W 93 W 200 W TOP260LN 147 W 190 W 93 W 140 W TOP261EN/YN/EG 177 W 333 W 118 W 254 W TOP261LN 177 W 244 W 118 W 177 W TOP262EN6 177 W 333 W 118 W 254 W TOP262LN6 177 W 244 W 118 W 177 W Table 1.

December 2021 TOP252-262 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 Description TOPSwitch™-HX 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. Y Package Option for TOP259-261 In order to improve noise-immunity on large TOPSwitch-HX Y package parts, the F pin has been removed (TOP259-261YN are fixed at 66 kHz switching frequency) and replaced with a SIGNAL GROUND (G) pin. This pin acts as a low noise path for the C pin capacitor and the X pin resistor. It is only required for the TOP259-261YN package parts. + AC DC IN OUT - Notes for Table 1: 1. 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. 2. Minimum continuous power in an open frame design at +50 °C ambient. 3. Peak power capability in any design at +50 °C ambient. 4. 230 VAC or 110/115 VAC with doubler. 5. Packages: P: DIP-8C, G: SMD-8C, M: SDIP-10C, Y: TO-220-7C, E: eSIP-7C, L: eSIP-7F. See part ordering information. 6. TOP261 and TOP262 have the same current limit set point. In some applications TOP262 may run cooler than TOP261 due to a lower RDS(ON) for the larger device. D TOPSwitch-HX V CONTROL C S XG PI-4973-122607 Figure 2.
