3 Description
The SN6507 is a high voltage, high frequency pushpull
transformer driver providing isolated power in a
small solution size. The device comes with the pushpull
topology’s benefits of simplicity, low EMI, and
flux cancellation to prevent transformer saturation.
Further space savings are achieved through dutycycle
control, which reduces component count for
wide-input ranges, and by selecting a high switching
frequency, reducing the size of the transformer.
The device integrates a controller and two 0.5-A
NMOS power switches that switch out of phase. Its
input operating range is programmed with precision
undervoltage lockouts. The device is protected
from fault conditions by over-current protection
(OCP), adjustable under-voltage lockout (UVLO), over
voltage lockout (OVLO), thermal shutdown (TSD), and
break-before-make circuitry.
The programmable Soft Start (SS) minimizes inrush
currents and provides power supply sequencing for
critical power up requirements. Spread Spectrum
Clocking (SSC) and pin-configurable Slew Rate
Control (SRC) further reduces radiated and conducted
emissions for ultra-low EMI requirements.
The SN6507 is available in a 10-pin HVSSOP DGQ
package. The device operation is characterized for a
temperature range from –55°C to 125°C.
