Infineon Technologies AG DC-DC Converters, Switching Regulators TLS4120D0EP V33

Description
The OPTIREG™ Switcher TLS4120D0EP V33 is a synchronous standalone step-down DC/DC-converter especially designed for automotive applications. The device has a current capability of 2 A, fixed 3.3 V output voltage and a feedback voltage accuracy of +/- 1.5% in PWM mode. Integrated power-stages, soft start feature and compensation reduce the required amount of external components and thus system costs and board space. The wide input voltage range (3.7 V – 35 V) and a 100% duty-cycle operation mode make the device suitable for battery cranking scenarios in automotive applications. The wide switching frequency range allows the selection of appropriated coils and capacitors. The switching frequency can be synchronized with an external clock signal. Spread spectrum frequency modulation can be activated to improve the EMI performance in PWM operation. The device is offering a low-current consumption in PFM mode at light loads to optimize the efficiency. In disabled mode, the current consumption is reduced to typically 1 μA. The TLS4120D0EP V33 is able to detect undervoltage and overvoltage conditions of the output voltage and indicates this with the reset output signal. Overcurrent and overload protections avoid excessive currents to protect the device during short circuit conditions at the buck converter output. The integrated thermal shutdown feature additionaly protects the device from overheating. Furthermore the enhanced PG-TSDSO-14 exposed-pad package enables an advantageous thermal performance in the application.
