TI's dual-output 200-mA power supply improves AMOLED displays

Aug. 11, 2010
Date Announced: 11 Aug 2010 DALLAS (August 11, 2010) – Texas Instruments Incorporated (TI) (NYSE:TXN) today introduced a new 200-mA dual output power supply designed to provide improved picture quality for active matrix OLED (AMOLED) displays that require positive and negative supply rails. The TPS65137 uses a low dropout (LDO) post regulator for line and load transient response with minimum output voltage ripples to provide stable picture quality. With its wide input range of 2.3 V to 5.5 V and small solution size of 3-mm x 3-mm QFN package and small external component count, the TPS65137 is suited for AMOLED displays in portable devices, such as mobile phones and smartphones. Order samples of the TPS65137 today: www.ti.com/tps65137-preu.Key features and benefits of the TPS65137• Wide input voltage range of 2.3 V to 5.5 V allows the device to accept higher positive input voltages than the positive output voltage and still maintain accurate regulation of one percent of the positive output voltage.• LDO post regulator for positive output to provide line and load transient response with minimum output voltage ripples to provide stable picture quality.• Advanced power save mode with out-of-audio control reduces switching frequency as the load current decreases and maintains high efficiency over the entire load current range without audible noise.• Digitally programmable negative output voltage from -2.2 V to -4.9 V in digital step.
