Voltage Mode PWM Controller 16-Pin VFQFPN EP T/R

The L6738A is a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to realize a DC-DC converter.The device flexibility allows to manage conversions with power input VINas low as 1.5V and the device supply voltage ranging from 5 V to 12 V bus.The L6738A features a proprietary algorithm that allows Light-Load efficiency optimization, boosting efficiency without compromising the output voltage ripple.The integrated 0.8 V reference allows generation of output voltages with ±0.5% accuracy over line and temperature variations.The oscillator is programmable up to 600 kHz.The L6738A provides a programmable overcurrent protection and overvoltage protection. The current information is monitored across the inductor DCR.The L6738A is available in a VFQFPN 16 3x3 mm package.
