Working Principle

The LTC1147LCS8-3.3#TRPBF utilizes synchronous mode regulation and pulse-width modulation (PWM) control. This synchronous mode operation eliminates the need for a large output capacitor and current sensing resistors, thus reducing design time and cost. The LTC1147LCS8-3.3#TRPBF implements a low-noise, fast-transient-response voltage regulator by sensing the output voltage of a buck converter and providing a feedback voltage to the MOSFET gate driver through an op amp in the feedback loop. The LTC1147LCS8-3.3#TRPBF also implements feedback voltage regulation to protect against over and input voltage. The output voltage can be set by an external voltage reference, such as a resistor divider network, or an internal reference.

The LTC1147LCS8-3.3#TRPBF also provides several protection features including over-voltage protection, thermal shutdown, current limit and guarding features. In addition, the LTC1147LCS8-3.3#TRPBF is designed to protect the MOSFET and output capacitor from damage due to repeated over-voltage and under-voltage cycles. The LTC1147LCS8-3.3#TRPBF also integrates a MOSFET gate driver, which simplifies board layout and improves the EMI performance of the power supply design.

Conclusion

The LTC1147LCS8-3.3#TRPBF is a highly integrated, cost-effective, and efficient DC/DC switching controller with a voltage regulator. It is suitable for many applications, including portable and battery-powered devices, medical electronics, lighting, and industrial and commercial systems. It provides sync mode regulation with PWM control, fast transient response, and enabling features such as current limit and over-voltage protection. The LTC1147LCS8-3.3#TRPBF is an ideal solution for power supply design of portable and low-power systems.
