Input range 15V to 100V. 2 FB Feedback Signal Inverting input for the internal error amplifier. The non-inverting input is connected to a 0.75V reference. 3 COMP Output of the Internal Error Amplifier There is an internal 5k Ω resistor pull-up on this pin. The error amplifier provides an active sink. 4 REF Precision 5 volt reference output Maximum output current: 10mA. Locally decouple with a 0.1µF capacitor. Reference stays low until the line UV and the V CC UV are satisfied. 5 HD Main Buck PWM control output Buck switch PWM control output. The maximum duty cycle clamp for this output corresponds to an off time of typically 240ns per cycle. The LM5101 or LM5102 Buck stage gate driver can be used to level shift and drive the Buck switch. 6 LD Sync Switch control output Sync Switch control output. Inversion of HD output. The LM5101 or LM5102 lower drive can be used to drive the synchronous rectifier switch. 7V CC Output from the internal high voltage start-up regulator. Regulated to 9 volts. If an auxiliary winding raises the voltage on this pin above the regulation setpoint, the internal start-up regulator will shutdown, reducing the IC power dissipation. 8 PUSH Output of the push-pull drivers Output of the push-pull gate driver. Output capability of 1.5A peak . www.national.com 2 |
