TPS65214 and TPS65215 are Power Management Integrated Circuits (PMICs) that have significant register map overlap with TPS65219 and each other. The series introduces the 2 new PMICs and restructures the existing driver to support multiple devices. - TPS65214, TPS65215, and TPS65219 each have 3 Buck regulators - TPS65214 has 2 LDOS and 1 GPO, whereas TPS65219 has 4 LDOs and 2 GPOs. - TPS65214's LDO1 maps to TPS65219's LDO3. - A key difference between TPS65215 & TPS65214 are the LDO current and voltage output ranges and the configurable options available. - TPS65215 has 2 LDOs, whereas TPS65219 has 4 LDOs. - TPS65215's LDO2 maps to TPS65219's LDO3. - TPS65215 has 1 GPO, whereas TPS65219 has 2 GPOs.
