Datasheet Rev. 2.1
1.2
The TLE 6389 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
TLE6389-2 GV can be shut down via the Enable input reducing the input current to
<2µA. The TLE 6389 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-conduction 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 (TLE6389-2 GV50 and
TLE6389-3 GV50) and adjustable for the TLE6389-2 GV. The version TLE6389-2 GV50
features a reset function with a threshold between 4.5V and 4.8V, including a small
hysteresis of typ. 50mV. In the version TLE6389-3 GV50 the device incorporates a reset
with a typ. 1V hysteresis. Input voltages of all TLE 6389 can be up to 60V.
