STMicroelectronics L6726A
L6726A is a single-phase step-down controller with integrated high-current drivers that provides complete control logic, protections and reference voltage to realize in an easy and simple way general DC-DC converters by using a compact SO-8 package. The integrated 0.8 V reference allows regulating output voltage with ±1% accuracy over line and temperature variations. L6726A provides simple control loop with transconductance error amplifier.| Part No. | L6726A |

● CPU and DSP power supply
● Distributed power supply
● General DC / DC converters SO-8
DESCRIPTION
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. Oscillator is internally fixed to 270 kHz. L6726A provides programmable over current protection. Current information is monitored across the low-side MOSFET RdsON saving the use of expensive and space-consuming sense resistors. FB disconnection protection prevents excessive and dangerous output voltages in case of floating FB pin. Table 1.
