TPS5100 Triple-Channel PWM Controller

The TPS5100 is a triple PWM control circuit, primarily designed to compose the power supply for LCD display. Each PWM channel has own error amplifier, PWM comparator, dead-time control and output driver. The trimmed voltage reference, oscillator, undervoltage lockout and short circuit protection are.
