† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:
1. All voltage values are with respect to the network ground terminal.
2. This rating is specified at duty 3 10% on output rise and fall each pulse. Each pulse width (rise and fall) for the peak current should not exceed 2 ms.
3. See Dissipation Rating Table for free-air temperature range above 25°C.


Description

The TPS5102 is a dual, high efficiency controller designed for notebook system power requirements. Under light load conditions, high efficiency is maintained as the controller switches from the PWM mode to the lower frequency Skip mode.

These two operating modes of TPS5102, along with the synchronous-rectifier drivers, dead-time, and very low quiescent current, allow power to be conserved and the battery life extended, under all load conditions.

The resistor-less current protection and fixed high-side driver voltage simplify the system design and reduce the external parts count. The wide input voltage range and adjustable output voltages allow flexibility for using the TPS5102 in notebook power supply applications.
