The step- down converters allow the use of small inductors and capacitors to achieve a small solution size. The TPS6507x devices also integrate two general purpose LDOs for an output current of 200 mA. These LDOs can be used to power an SD-card interface and an always-on rail, but can be used for other purposes as well. Each LDO operates with an input voltage range from 1.8 V to 6.3 V allowing them to be supplied from one of the step-down converters or directly from the main battery. An inductive boost converter with two programmable current sinks power two strings of white LEDs. The TPS6507x devices come in a 48-pin leadless package (6-mm × 6-mm VQFN) with a 0.4-mm pitch. 6 Device Options OUTPUT VOLTAGE AT OUTPUT OUTPUT CURRENT AT OUTPUT VOLTAGE PGOOD, TOUCH SCREEN VOLTAGE AT DCDC1 PART NUMBER (1) AT LDO1 / LDO2 RESET DELAY CONTROLLER DCDC1 / DCDC2 / DCDC3 DCDC3 DCDC2 1 V / 1.2 V 3.3 V 1.8 V / 1.2 V 0.6 A / 1.5 A / 1.5 A 400 ms Yes TPS65070RSL (OMAP-L1x8) 1.8 V / 3.3 V 1.2 V / 1.4 V 3.3 V 1.2 V / 1.2 V 3 x 600 mA 20 ms No TPS65072RSL (Atlas IV) 1.8 V / 2.5 V 1.2 V / 1.35 V 1.8 V 0.6 A / 0.6 A / 1.5 A 1.8 V / 1.8 V 400 ms Yes TPS65073RSL (OMAP35xx) 1.2 V / 1.8 V External sequencing 1.2 V / 1.35 V 1.8 V 0.6 A / 0.6 A / 1.5 A 1.8 V / 1.8 V 400 ms Yes TPS650731RSL (OMAP35xx) 1.2 V / 1.8 V Internal sequencing 1.2 V / 1.35 V 1.8 V 0.6 A / 0.6 A / 1.5 A 1.8 V / 1.8 V 400 ms Yes TPS650732RSL (AM3505) 1.8 V / 3.3 V Internal sequencing (1) The RSL package is available in tape and reel.
