DESCRIPTION The ZCC6601 is a monolithic oscillator/power-driver, specifically designed for small form factor, isolated power supplies in isolated interface applications. It drives a low-profile, center-tapped transformer primary from a 3.3 Vor 5 V DC power supply. The secondary can be wound to provide any isolated voltage based on transformerturns ratio. The ZCC6601 consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive the ground referenced N-channel power switches. The internal logic ensures break-before-make action between the two switches. The ZCC6601 is available in a small SOT23-5 package, and is specified for operation at temperatures from –40°C to 125°C. FEATURES • Push-Pull Driver for Small Transformers • Single 3.3 V or 5 V Supply • High Primary-side Current Drive: – 5 V Supply: 650 mA (max) – 3.3 V Supply: 450 mA (max) • Low Ripple on Rectified Output Permits Small Output Capacitors • Soft start and Current limit • Thermal shutdown • Small 5-pin SOT23 Package • Short circuit protection • Over temperature protection APPLICATIONS • Isolated Interface Power Supply for CAN, RS- 485, RS-422, RS-232, SPI, I2C, Low-Power LAN • Industrial Automation • Process Control • Medical Equipment
