Device description
L6728A is a single-phase PWM controller with embedded high-current drivers that provides
complete control logic and protections to realize in an easy and simple way a general DC-
DC step-down converter. Designed to drive N-channel MOSFETs in a synchronous buck
topology, with its high level of integration this 10-pin device allows reducing cost and size of
the power supply solution also providing real-time PGOOD in a compact
VFQFPN10 3x3 mm.
L6728A is designed to operate from a 5 V or 12 V supply. The output voltage can be
precisely regulated to as low as 0.8 V with ±1 % accuracy over line and temperature
variations. The switching frequency is internally set to 600 kHz.
This device provides a simple control loop with a voltage-mode error-amplifier. The error-
amplifier features a 15 MHz gain-bandwidth product and 8 V/µs slew rate, allowing high
regulator bandwidth for fast transient response.
To avoid load damages, L6728A provides over-current protection as well as overvoltage,
under voltage and feedback disconnection protection. The over-current trip threshold is
programmable by a simple resistor connected from Lgate to GND. Output current is
monitored across low-side MOSFET RDS(on), saving the use of expensive and space-
consuming sense resistor. Output voltage is monitored through dedicated VSEN pin.
L6728A implements soft-start increasing the internal reference in closed loop regulation.
low-side-less feature allows the device to perform soft-start over pre-biased output avoiding
high current return through the output inductor and dangerous negative spike at the load
side.
L6728A is available in a compact VFDFN10 3 x 3 mm package with exposed pad.
