ON Semiconductor Introduces Low Power, High Efficiency DC-DC Converter Optimized for Low Load Efficiency
Ideal for power savings in consumer electronics for home and office applications
Embedded World - NUREMBERG, Germany. – ON Semiconductor Corporation (Nasdaq: ONNN), driving innovation in energy efficiency, has introduced the LV5980MC, a 3 ampere (A) step down DC-DC converter integrated circuit (IC) that improves conversion efficiency at light load. In consumer electronics designs, the device is able to reduce energy consumption during standby mode.
The LV5980MC regulates input voltages from 4.5 volts (V) to 23 V down to an output voltage as low as 1.235 V. Combining a low consumption power saving feature, (the device shows an operating current of 63 micro amps (uA), with both pulse-width modulation (PWM) and pulse-frequency modulation (PFM), the device can achieve 80 percent efficiency at an output current of 2 milliamps (mA) in typical applications. The device also includes an internally fixed switching frequency of 370 kilohertz (kHz), high-side MOSFET of 100 milliohms (mΩ) and is able to supply up to 3.0 A of load current.
“Consumer electronics for the home or office are required to be power saving and one of the key requirements in doing so is reducing power consumption in standby mode,” said Kenichi Nakajima, director of ON Semiconductor’s SANYO LSI product division. “The LV5980MC, with its integrated power save feature, improves conversion efficiency at light load, providing an effective and efficient solution.”
Packaging and Pricing
The LV5980MC is offered in a SOIC-8 package and budgetary priced at $0.7 USD per unit in 2,500 unit quantities.
