SO-8 Maturity status link A6727B A6727B Datasheet Automotive single-phase PWM controller Features AEC Q100 qualified grade 1 Flexible power supply from 5 V to 12 V Power conversion input as low as 1.5 V ± 1.5 % output voltage accuracy High-current integrated drivers Adjustable output voltage 0.8 V internal reference Simple voltage mode control loop Sensorless and programmable OCP across Low-side RDS(on) Oscillator internally fixed at 300 kHz Internal soft-start LS-less to manage pre-bias startup Disable function OV/UV protection FB disconnection protection SO-8 package Applications Dedicated to automotive applications Description The A6727B is a single-phase step-down controller with integrated high-current drivers that provides complete control logic, protection and reference voltage to realize a general DC-DC converter by using a compact SO-8 package. The device flexibility allows the management of conversions with power input VIN as low as 1.5 V and device supply voltage in the range of 5 V to 12 V. The A6727B provides simple control loop with voltage mode error-amplifier. The integrated 0.8 V reference allows the regulation of output voltages with ±1.5 % accuracy over temperature variations. The oscillator is internally fixed to 300 kHz. The A6727B provides programmable overcurrent protection as well as over and undervoltage protection. The current information is monitored across the low-side MOSFET RDS(on) savin...
