1 / 32 page  September 2007 Rev 2 1/32 1 L6728 Single phase PWM controller with PowerGOOD Features ■ Flexible power supply from 5V to 12V ■ Power conversion input as low as 1.5V ■ 0.8V internal reference ■ 0.8% output voltage accuracy ■ High-Current integrated drivers ■ PowerGOOD output ■ Sensorless and programmable OCP across Low-Side RdsON ■ OV / UV protections ■ VSEN disconnection protection ■ Oscillator internally fixed at 300kHz ■ LS-LESS to manage pre-bias start-up ■ Adjustable output voltage ■ Disable function ■ Internal Soft-Start ■ VFQFPN 10 package Applications ■ Memory and termination supply ■ Subsystem power supply (MCH, IOCH, PCI...) ■ CPU & DSP power supply ■ Distributed power supply ■ General DC / DC converters Description L6728 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 VFQFPN 10 package. Device flexibility allows managing conversions with power input VIN as low as 1.5V and device supply voltage ranging from 5V to 12V. L6728 provides simple control loop with voltage mode EA. The integrated 0.8V reference allows regulating output voltages with ±0.8% accuracy over line and temperature variations. Oscillator is internally fixed to 300kHz. L6728 provides programmable dual level over current protection as well as over and under voltage protection. Current information is monitored across the Low-Side MOSFET RdsON saving the use of expensive and space- consuming sense resistors. PGOOD output easily provides real-time information on Output Voltage status, through VSEN dedicated output monitor. VFQFPN 10 Table 1.
