LINEAR INTEGRATED CIRCUIT
VERTICAL DEFLECTION
BOOSTER
„
DESCRIPTION
The UTC T8177 is a vertical deflection booster integrated circuit
and designed for CRT monitors and high performance TVs. It is
intended to delivers flyback voltages up to 70V.
The T8177 supplies with up to 35V and provides a maximum
output current up to 3.0A peak to peak to drive the deflection yoke
with a high efficiency.
The UTC T8177 is offered in HEPTAWATT package.

Notes: 1. Reference to GND pin.
2. For t ≤ 10μS, IO can be up to 4A peak to peak (up to 120Hz).
3. Provided output transistor SOA (see Figures 1 and 2).
4. Equivalent to discharging a 100pF capacitor through a 1.5kΩ series resistor.
5. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
