The LTC3535EDD#PBF is a 2.5V to 5.5V Input, 2.2V Output, 1.5-A Step-Down DC-DC Switching Regulator. Its key feature is its small Footprint, flexibility and low power consumption. This regulator offers a wide application field that covers from portable devices to industrial equipments.

Regulator Introduction

The LTC3535EDD#PBF is a cost-effective regulating integrated circuit (IC) purpose built for a variety of applications where a steady, low output voltage is desired. It integrates a high-performance step-down switching voltage regulator, a high frequency inductor, and other components that required to design a DC-DC converter capable of providing up to 1.5A continuous load current. Suitable for a wide input voltage range, the regulator’s output voltage can be regulated to a non-programmable set point.

It also contains an internal current limit and auto re-start functions, which limit the output current and regulate the output voltage during over-load conditions. These functions provide a higher level of system protection and flexibility when used with a larger current output.

System Design

The LTC3535EDD#PBF is designed to meet a range of system designs, including low-noise voltage regulator and supply networks, peripherals and other power conversion circuits. When used in conjunction with a high-frequency flyback converter, the regulator’s input voltage range can be increased to 12V, for higher loads. The regulator also provides a low-power conversion efficiency of up to 95% with its high-performance, high-efficiency switching circuit.

This device is designed for use in a variety of applications including cell phone, laptop, and portable device chargers, battery backup systems, and other regulators. The regulator also comes with a fixed output voltage, so power-hungry applications such as laptops and gaming consoles are not suitable for this regulator.

Working Principle

The LTC3535EDD#PBF works on the principle of buck-boost inductor-based switching regulators that step down the input voltage to a lower regulated output voltage. When the voltage at the input cycle is higher than the output voltage, the regulator steps down the voltage by pulse-width-modulated (PWM) conversion. The switching regulator uses a high-frequency period, or duty cycle of the switching frequency, to convert AC power to DC power. During the cycle, the PWM process charges the control input and then transfers it to the output. During the other part of the cycle, the power is discharged from the output.

The level-shifted gate drive sector enables the device to operate in both buck and boost modes, allowing for seamless transition from one mode to another. In maintaining the output voltage, the regulator takes into account the load current, input voltage and operating conditions. It is capable of providing a wide input voltage range, making it suitable for solar-panel applications and other conversion systems that require multiple input sources.

Conclusion

The LTC3535EDD#PBF is a cost-effective and reliable DC-DC step-down regulator that is specially designed for a wide range of applications requiring a low output voltage. Its high-frequency switching regulator, PWM conversion, and buck-boost inductor capabilities make it an ideal choice for a number of different types of power conversion needs. The small footprint, flexible and low power consumption of the device make it an attractive option for a variety of different uses.
