TPS5100 Datasheet (Texas Instruments) - Triple-Channel PWM Controller

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
