PMIC- Voltage Regulators - DC DC Switching Regulators

The LTC1174CS8-5#PBF is a type of DC-DC switching regulator used to provide highly efficient step-down power conversion from a source voltage to a lower regulated output voltage. It features an internal current limit circuit and supports a wide input voltage range from 5 V to 36 V DC. This device is suitable for use in a variety of applications ranging from battery-powered systems to server and telecom rack power-supply designs. The LTC1174CS8-5#PBF is designed with a synchronous rectifier boost converter switch to provide 3 A (300 mA/phase) of continuous output current. This device is powered by a low voltage supply of up to 36 V DC and has a maximum power rating of 150 W. The LTC1174CS8-5#PBF is available in an 8-pin, surface-mount SOIC package and is RoHS/REACH-compliant.

Applications

The LTC1174CS8-5#PBF is ideal for a host of applications, including powering of portable devices, automotive and industrial heavy-duty applications. Additionally, this device can be used in systems where the output voltage needs to be regulated at a very low level with a high load current or systems where the input voltage must operate over a wide range of conditions.The LTC1174CS8-5#PBF offers many advantages compared to linear voltage regulators and makes it a great choice for applications which require a high efficiency and good power density. It is capable of delivering very low quiescent currents, and supports a wide range of input voltages and output currents. This device also features an internal current limit circuit and has very low EMI generation and low noise performance.

Working Principle

The LTC1174CS8-5#PBF is a synchronous rectifier boost converter switch which operates by extracting energy stored in an inductor and transferring it to the load using switches. It has an internal low-side switch and a high-side switch which drive the inductor current up and down accordingly.When the high-side switch is closed, energy is stored in the inductor and the output voltage rises. When the low-side switch is closed, the inductor current flows to ground and the output voltage is decreased. This cycle is repeated and the output voltage is maintained at a relatively constant level.The LTC1174CS8-5#PBF also features an internal current limit circuit which provides a current limiting effect by opening the high-side switch when the current reaches a certain threshold. This device also supports operation with a wide range of input voltages and can accept input voltages ranging from 5 V DC to 36 V DC.

Conclusion

The LTC1174CS8-5#PBF DC-DC switching regulator from Linear Technology is a great choice for systems where the output voltage needs to be regulated at a very low level with a high load current or systems where the input voltage must operate over a wide range of conditions. This device offers very low quiescent currents, an internal current limit circuit, and a wide range of input voltages and output currents. It also has very low EMI generation and low noise performance and is ideal for powering of portable devices, automotive and industrial heavy-duty applications.
