Texas Instruments introduced a 200-mA 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.

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.
