It delivers a programmable step up voltage (Boost) and a precise 5 V fully short circuit protected output voltage (Buck). The TLE 6711 G contains a power on reset feature to start up the system, an integrated digital window watchdog to monitor the connected microcontroller and a system enable output to indicate the microcontroller window watchdog faults. The device is based on Infineon’s power technology SPT® which allows bipolar and CMOS control circuitry to be integrated with DMOS power devices on the same monolithic circuitry. The very small P-DSO-14-3 SMD packages meet the application requirements. Furthermore, the build-in Features like under- and overvoltage lockout for boost- and Data Sheet V 2.22 1 2001-04-23 TLE 6711 Overview buck-voltage and the overtemperature shutdown feature increase the reliability of the TLE 6711 G supply system.
