3 Description
The SN6507-Q1 is a high voltage, high frequency
push-pull transformer driver providing isolated power
in a small solution size. The device comes with
the push-pull topology’s benefits of simplicity, low
EMI, and flux cancellation to prevent transformer
saturation. Further space savings are achieved
through duty-cycle 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-Q1 is available in a 10-pin HVSSOP
DGQ package. The device operation is characterized
for a temperature range from –55°C to 125°C.
