Infineon Technologies AG DC-DC Converters, Switching Regulators TLE6389-2GV

Description
The TLE6389-2GV step-down DC-DC switching controllers provide high efficiency over loads ranging from 1mA up to 2.5A. A unique PWM/PFM control scheme operates with up to a 100% duty cycle, resulting in very low dropout voltage. This control scheme eliminates minimum load requirements and reduces the supply current under light loads to 120μA, depending on dimensioning of external components. In addition the adjustable version TLE6389-2GV can be shut down via the Enable input reducing the input current to <2μA. The TLE6389 step-down controllers drive an external P-channel MOSFET, allowing design flexibility for applications up to 12.5W of output power. A high switching frequency and operation in continuous-conductio n mode allow the use of tiny surface-mount inductors. Output capacitor requirements are also reduced, minimizing PC board area and system costs. The output voltage is preset at 5V (TLE6389-2GV50 and TLE6389-3GV50) and adjustable for the TLE6389-2GV. The version TLE6389-2GV50 features a reset function with a threshold between 4.5V and 4.8V, including a small hysteresis of typ. 50mV. In the version TLE6389-3GV50 the device incorporates a reset with a typ. 1V hysteresis. Input voltages of all TLE6389 can be up to 60V. Summary of Features Input voltage range from < 5V up to 60V Adjustable output voltage: 7V to 15V Output voltage accuracy: 3% Output current up to 2.3A 100% maximum duty cycle Less than 120μA quiescent current at low loads1 2μA max. shutdown current at device off (TLE 6389-2 GV) Fixed 360kHz switching frequency Frequency synchronization input for external clocks Current Mode control scheme Integrated output under voltage Reset circuit On chip low battery detector (on chip comparator) Automotive temperature range -40°C to 150 °C Green Product (RoHS compliant) AEC qualified Benefits Suitable as well for truck systems (24V-net) low drop-out by 100%DC Suitable for permanently Vbat-connected systems Reset generator controlling µC Potential Applications Body Cluster General purpose
