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.

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.
