Semtech Corporation, a provider of high-performance semiconductors, Internet of Things systems and cloud connectivity services, announced the launch of LoRa Connect LR1121, a new transceiver for Internet of Things endpoints that offers lower power consumption, global connectivity and long-distance communication, extending its market-leading LoRa portfolio.
SC4524B is a constant-frequency peak-current mode step-down switching regulator in an SOIC-8 EDP package capable of producing 2A output current from 3V to 18V inputs. SC4524B is suitable for next generation XDSL modems, HDTVS and a variety of load point applications. And the use of peak current PWM control, to achieve fast transient response, loop compensation is simple.
The SC2545 is a high performance dual PWM controller. It is designed to convert a wide ranged input voltage down to two independent output rails. The SC2545 support “peel off ” tracking for the two outputs at start up which means the two outputs ramp up together till the one with lower output level reaching the regulation.
The SC4201 is a multiphase link controller designed for isolated and non-isolated applications. Its operating frequency can be programmed to exceed 2MHz per phase (oscillator frequency = phase frequency multiplied by the number of phases 3 or 4), and can be easily synchronized with external, faster frequencies.
The SC4215 is a high-performance positive regulator designed for applications requiring very low input voltage and very low voltage drop (up to 2 amps). Its Vin voltage is as low as 1.6V, and its output voltage is programmable as low as 0.8V. The SC4215 has an ultra-low drop out, which is very suitable for Vout applications that are very close to Vin
LoRa and LoRaWAN have jointly defined a low-power, wide-area (LPWA) networking protocol designed to wirelessly connect battery-operated devices to the Internet over regional, national, or global networks. They address key requirements for the Internet of Things, such as two-way communication, end-to-end security, mobile and localized services.
