Additional Infomation About Product

L6726A Single phase PWM controller Feature Flexible power supply from 5 V to 12 V Power conversion input as low as 1.5 V 1% output voltage accuracy High-current integrated drivers Adjustable output voltage SO-8 0.8 V internal reference Sensorless and programmable OCP across Low-side R Description dsON Oscillator internally fixed at 270 kHz L6726A is a single-phase step-down controller Programmable soft-start with integrated high-current drivers that provides complete control logic, protections and reference Ls-less start up voltage to realize in an easy and simple way Disable function general DC-DC converters by using a compact FB disconnection protection SO-8 package. SO-8 package Device flexibility allows managing conversions with power input V as low as 1.5 V and device IN supply voltage ranging from 5 V to 12 V. L6726A provides simple control loop with trans- conductance error amplifier. The integrated 0.8 V Applications reference allows regulating output voltage with 1% accuracy over line and temperature Subsystem power supply (MCH, IOCH, PCI...) variations. Oscillator is internally fixed to 270 kHz. Memory and termination supply L6726A provides programmable over current CPU and DSP power supply protection. Current information is monitored Distributed power supply across the low-side MOSFET R saving the dsON use of expensive and space-consuming sense General DC / DC converters resistors. FB disconnection protection prevents excessive and dangerous output voltages in case of floating FB pin. Table 1.
