简述:
1 A triple-output AMOLED display power supply
-
描述:
NEX10058 is designed for powering AMOLED (Active-Matrix Organic LED) displays which require ELVDD, ELVSS and AVDD.
It integrates a boost converter for ELVDD, an inverting buck-boost converter for ELVSS and a boost converter for AVDD. Output voltages of all the three converters can be programmed in digital steps through the digital interface control pins (ASWIRE and ESWIRE).
The device features high efficiency and excellent line and load regulation and transient performance which are well suited for AMOLED applications and is critical to battery-powered applications supply. It features an enhanced output current capability of up to 1 A with precise output voltage accuracy, resulting in higher brightness and superior display performance for AMOLED screens.
NEX10058 is available in a green WLCSP25 package.
