The EVM generates 3.3-V and 5-V LDO output from a wide input range of 5.5 V to 28 V. The rated current for each output is 100 mA. The EVM also delivers an always-on 3.3-V, 5 m-A output. The glitch-free switchover function offers better system efficiency under light load conditions. When the switchover function is enabled, the LDO load is supplied by an external input source that eliminates the power loss generated as a result of the voltage drop across the LDO. A 250-kHz clock is generated for the charge pump feature. The clock is enabled when 5VIN is greater than 2 V. On the EVM, 15V_OUT is generated by a charge pump and is only available when 5VIN is applied and the 250-kHz clock is generated.
