            TPS40304 3V to 20V Input Synchronous Buck Controller
                    Texas Instruments' TPS40304 reduces output capacitance requirements for tight regulation point of load converters
    

TPS40304 3V to 20V Input Synchronous Buck Controller Texas Instruments' TPS40304 is a cost-optimized synchronous buck controller that operates from 3 V to 20 V (input). This controller implements voltage-mode control architecture with input-voltage feed-forward compensation that responds instantly to input voltage change. The switching frequency is fixed at 600 KHz. The frequency spread spectrum feature adds dither to the switching frequency, significantly reducing the peak EMI noise and making it much easier to comply with EMI standards. The TPS40304 offers design with a variety of user programmable functions, including soft-start, over-current protection (OCP) levels, and loop compensation. OCP level may be programmed by a single external resistor connected from LDRV pin to circuit ground.
