The compact layout of the TPS6512x uses a single inductor to generate independently-regulated positive and negative outputs. A free-running variable peak current PWM control scheme time-multiplexes the inductor between outputs. This control architecture operates at a pseudo-fixed-frequency to provide fast response to line and load transients while maintaining a relatively constant switching frequency and high efficiency over a wide range of input and output voltages. Due to the high switching frequency capability of the device, inexpensive and ultra-thin 8.2 or 10µH inductors can be used. The main output, V , is post-regulated to provide a low-ripple source drive voltage for the LCD display. The MAIN auxiliary outputs generate a boosted output voltage, V , up to 20 V, and a negative output voltage, V , down to GH GL -18 V for the LCD gate drive. The device has internal current limiting for high reliability under fault conditions. Additionally, the device offers a fixed output linear regulator for the LCD logic circuitry. 100 90 TPS65123 D1 80 V GL VIN SWN V IN R3 C1 down to −18 V/2 mA 70 2.7 V to 5.5 V L1 2.2 μ F RUN C3 60 10μH EN R4 100 nF SWP 50 GATE FBL 40 V V GH MAIN VGH VMAIN R5 30 up to 20 V/2 mA 3.0 V to 5.3 V/25 mA FBM R1 C2 BOOT C5 20 FBH 100 nF R6 C4 220 nF 10 R2 1μ F 0 PGND AGND V − Input Voltage − V A A IN I − Load Current − mA BOOT Figure 1.
