F 01/09 2 TOP252-262 www.powerint.com 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. • • • • • • PI-4973-122607 AC IN DC OUT D S C TOPSwitch-HX CONTROL V + - G X Figure 2. Typical Flyback Application TOP259YN, TOP260YN and TOP261YN. 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. 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 R DS(ON) for the larger device. 7. TOP256E package parts are available with Green (Halogen Free) mold compound. See Part Ordering Information on page 47. Parametrically green material encapsulated E package parts are identical to non-green parts. |
