Product Summary

The TOP209P is a Three-terminal Off-line PWM Switch. The TOP209P implements all functions necessary for an off-line switched mode control system: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated oscillator, high voltage start-up bias circuit, bandgap derived reference, bias shunt regulator/error amplifier for loop compensation and fault protection circuitry. Compared to discrete MOSFET and controller or self oscillating (RCC) switching converter solutions, a TOP Switch integrated circuit can reduce total cost, component count, size, weight and at the same time increase efficiency and system reliability.

Parametrics

TOP209P absolute maximum ratings: (1)DRAIN Voltage: -0.3 to 700 V; (2)CONTROL Voltage: -0.3 V to 9 V; (3)CONTROL Current: 100 mA; (4)Storage Temperature: -65 to 150℃; (5)Operating Junction Temperature: -40 to 150℃; (6)Lead Temperature: 260℃; (7)Thermal Impedance (θJA): 100℃/W; (8)Thermal Impedance (θJC): 40℃/W.

Features

TOP209P features: (1)Cost Effective Switcher for Low Power Applications; (2)Replaces linear power supplies; (3)Replaces discrete switcher and 20 to 50 components– cuts cost, increases reliability; (4)Stand-by power supplies for Green or energy efficientproducts such as personal computers, monitors, UPS, copiers, fax machines, etc.; (5)Housekeeping or "keep-alive" power supply applicationssuch as TV, appliances, industrial control and personalcomputers; (6)Meets "Blue Angel" low power stand-by specification; (7)Controlled MOSFET turn-on reduces EMI and EMI filtercosts; (8)80% smaller and lighter compared to linear supply; (9)50% smaller compared to discrete.
