4-bit DAC, Simple PWM Power Regulator With Linear Controller
FEATURES
Switching Regulator and Low Dropout Linear Regulator on Single Chip. Simple Voltage-Mode PWM Control. Fast Transient Response. ±1.5% 4-Bit Digital-to-Analog Output Voltage. Adjustable Current Limit Without External Sense Resistors. Full 0% to 100% Duty Ratio. 200KHz Free-Running Oscillator Programmable up to 350KHz. Power-Good Output Voltage Monitor. Short Circuit Protection with Low Short Circuit Output Current. The internal 4-bit Digital-to-Analog Converter (DAC) adjusts the output voltage from 2.0V to 3.5V in 0.1V increments. The precision reference and voltage-mode control can provide output
