The S-1165B52MC-N7LTFG is an advanced DC-DC buck-boost power converter that belongs to the PMIC - Voltage Regulators - Linear category. Its main purpose is to convert a low voltage input to an adjustable output voltage ranging from 0.925V to any voltage below 5.5V. This product is designed for high efficiency, low complexity and low cost applications with moderate power rating.

The S-1165B52MC-N7LTFG uses advanced Single-Switch Buck-Boost Control Algorithm (SSBB) in order to provide a very high efficiency with wide Vin and Vout range and constant output current over the whole operating range. The SSBB control algorithm also allows relatively good transient response, making this module an ideal choice when an output voltage change is required.

The major applications of S-1165B52MC-N7LTFG are portable consumer electronics, wearable electronics and sensors, such as wearables, sport devices, media players, portable medical devices and consumer smart phones. The wide VIN and VOUT operating range makes this modular perfect for applications with varying external power sources, such as batteries. Furthermore, the low quiescent current, low output voltage ripple and low switching noise make this module suitable for powering noise-sensitive systems.

The S-1165B52MC-N7LTFG utilizes Synchronous Rectified Buck-Boost controller, a high-performance D-CAP2 mode control that meets the performance requirements of most DC/DC buck-boost converters. This controller provides an accurate steady-state control over a wide operating range, allowing high-efficiency conversion over the entire input voltage range. This results in an output voltage accuracy of +/-1.5%.

On the other hand, the S-1165B52MC-N7LTFG features a short-circuit protection and internal thermal protection that prevents output over-voltage protection, over-current protection and over-temperature protection, thus preventing the module from being damaged if it’s subjected to extreme conditions or misuse.

Also included as part of the design is under-voltage lockout (UVLO) feature. The UVLO feature is an important safety feature that prevents the circuit from being operated with a supply voltage lower than its specified voltage range. This feature will help to protect the circuit and its components from unexpected voltage drops.

Finally, the S-1165B52MC-N7LTFG uses a synchronous rectified buck-boost regulator, this is a high-performance controller that utilizes an Internal Digital Multi-Phase Control (DMPC) method to generate PWM waveforms for both the high- and low-side power device MOSFETs. This allows for higher efficiency and higher switching frequencies, improving overall performance. Furthermore, this regulator features programmable output voltage, which is adjustable from 0.925V to 5.5V via an external resistor.

Overall, the S-1165B52MC-N7LTFG is an excellent choice for a wide variety of applications such as portable consumer electronics and other wearables. Its features and performance characteristics make it the perfect choice for providing reliable and efficient voltage regulation. Furthermore, its wide Vin and Vout operating range and low cost make this solution ideal for a wide range of applications.
