L6728AH High frequency single phase PWM controller with Power Good

L6728AH is a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to realize in a simple way general DC-DC converters by using a compact VFDFPN 10 package.

Device flexibility allows managing conversions with power input VIN as low as 1.5 V and device supply voltage ranging from 5 V to 12 V.

L6728AH provides simple control loop with voltage mode EA. The integrated 0.8 V reference allows regulating output voltages with ±0.8% accuracy over line and temperature variations.

Oscillator is internally fixed to 600 kHz.

L6728AH provides programmable dual level over current protection as well as over and under voltage protection. Current information is monitored across the low-side MOSFET RDS(on) saving the use of expensive and spaceconsuming sense resistors.

PGOOD output easily provides real-time information on output voltage status, through VSEN dedicated output monitor
