SN6501 Transformer Drivers

Texas Instruments offers its SN6501, low-noise, 350 mA, 410 kHz transformer drivers for isolated power supplies

Image of Texas Instruments' SN6501 Transformer DriversTexas Instruments' SN6501 is a monolithic oscillator/power-driver, specifically designed for small form factor, isolated power supplies in isolated interface applications. The device drives a low-profile, center-tapped transformer primary from a 3.3 V or 5 V DC power supply. The secondary can be wound to provide any isolated voltage based on transformer turns ratio.

The SN6501 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 SN6501 is available in a small, SOT-23 (5) package and is specified for operation at temperatures from -40°C to 125°C.

Features
  • Push-pull driver for small transformers
  • High primary-side current drive:
    • 5 V supply: 350 mA (max.)
    • 3.3 V supply: 150 mA (max.)
  • Single 3.3 V or 5 V supply
  • Low ripple on rectified output permits small output capacitors
  • Small, 5-pin, SOT-23 package
