SOUTHCHIP SEMICONDUCTOR SC6104 PRELIMINARY DATASHEET INTERNAL USE CONFIDENTIAL Triple-Output Power Supply for AMOLED 1 DESCRIPTION 2 Features The SC6104 is a triple-channel switching mode power - supply which is designed to drive AMOLED displays - requiring VELVDD, VELVSS, and VAVDD. - It integrates a boost converter for VELVDD, an inverting - buck-boost converter for VELVSS and a boost converter for VAVDD. The output voltage is highly precise and can be - programmed by the external signal. - 2.5V to 4.6V Input Voltage Range ELVDD Output Voltage 4.6V~5.6V, 0.5% Accuracy ELVSS Output Voltage -1.4V~ -6.4V, 1% Accuracy 1.2A Output Current Capability for ELVDD&ELVSS AVDD Output Voltage 5.8V~7.9V, 1% Accuracy 0.15A Output Current Limit for AVDD For the portable devices applications, size, power - consumption and reliability are always in the first - consideration. The SC6104 uses a tiny package and it switches at a high frequency to minimize the inductor - and the capacitor size. Besides, synchronous rectification - (each rail) and Dual-phase (ELVSS only) topologies are - used to maximize the power efficiency. - The SC6104 uses innovative technology enabling excellent line and load regulation. All the output rails - allow being programmed by MC pin in digital steps. - Programmable Fast Discharge Input to Output，Output to Input Isolation Internal Soft Start to Limit Inrush Current Dual-phase operation for ELVSS Rail External Output Sense for ELVDD Under Voltage Protection Over Current Protection Over Load Protection The device integrates SCP, OTP, UVLO, and OCP to - protect itself from abnormal condition. - Short Circuit Protection Thermal Shutdown The SC6104 adopts 32 pin QFN 4x4 package. - Package: 4×4×0.75mm, 32Pin QFN 3 APPLICATIONS - AMOLED Displays ≧ 8...
