The LTC3615EFE-1#PBF application field include networking devices,industrial automation and automotive electronics,it has significantly decreased power loss and system costs. Moreover, it also reduce DCDC output ripple and enhances reliable system performance.The LTC3615EFE-1#PBF regulates multiple output voltages in proportion to a single reference voltage from zero to a maximum positive and negative value, through two step-down converters with voltage-mode operation. The two converters, connected either in series or parallel, can directly supply output voltage range from -60 V to +60V. The output current of each converter is controlled by the chip\'s internal control circuitry and fed back to the analog-digital converter channel. The LTC3615EFE-1#PBF buck converter output current sense is an integrated shunt resistor inside the converter. The integrated FET limiting and hiccup protection circuitry that allows maximum load current limit. The output voltage levels are set via an external VCC voltage setting pin. The VCC pin also provide a hard transition between Operational and Burst Mode Regulator operation. In terms of the workflow, the LTC3615EFE-1#PBF PMIC – Voltage Regulators – DC DC Switching Regulators, firstly starts with a stationery MCU enters the system, Then it becomes stay in a standby power state. In this state, the voltage regulator holds a low power state, which ends at the later step when MCU is needed to optimize power management efficiency and reduce the no-load power state. Finally, the current will be transformed into a steady current by the two-step down converter, then through the limit check, to ensure the stable output voltage, and is set and monitored by the µControllers internal programming process. The communication between MCU controllers and external power supply systems occurs through I2C or PMBus.The LTC3615EFE-1#PBF PMIC – Voltage Regulators – DC DC Switching Regulators can be operated in a wide-input range with a remarkable spectrum of powered applications. Its low voltage rating ensures it relative safety when making adjustments due to its solid integration of safety features. In terms of its equalization, efficiency and power density, this converter module also provides ruggedness,reliability and high-accuracy regulating steadily.LTC3615EFE-1#PBF PMIC – Voltage Regulators – DC DC Switching Regulators is an ideal product for distributed power consumption and offer optimal performance, high current,high voltage,high power density,crystal-clear energy efficiency,reliable system performance. It also provides customer with very low static current/no load and a large input voltage range.
