The LTC1159IS-5#PBF is a highly integrated IC component manufactured by Linear Technology (now part of Analog Devices Inc.), a leading semiconductor company. It is a dual, high efficiency, step-down (buck) switching regulator that operates with an input voltage range of 2.3V to 18V. The device is specifically designed for low power applications that require high efficiency operation.
One of the key features of the LTC1159IS-5#PBF is its ability to provide two independent, adjustable output voltages ranging from 1.24V to the input voltage. Each output can deliver a continuous current of up to 800mA. The device incorporates a constant frequency current mode architecture that ensures stable and predictable operation under various load conditions.
The LTC1159IS-5#PBF offers a wide range of important features to enhance its performance. It includes integrated power switches with low RDS(ON) to minimize power losses and improve efficiency. Additionally, it employs synchronous rectification to further enhance efficiency by reducing the reverse recovery losses. The switching frequency can be programmed externally, allowing flexibility to optimize efficiency or minimize component size.
To ensure protection and reliability, the LTC1159IS-5#PBF incorporates a variety of built-in safety features. It includes over-temperature and overcurrent protection circuits to prevent damage caused by excessive temperature or current conditions
