DCDC converter with dual supply

Question

Hi, 
 May I know if ADI has any similar component for LTC3260? 
 Was thinking whether the LTC3265 can be used as an alternative solution as LTC3260.. 
 Input 24V, output >&plusmn;12V 
 
 Thanks.

Hi Clt, 
 LTC3265 has a boost charge pump which only has a max input of 16V. It also means you cannot produce a stepped down +12V output. 
 However, the inverting charge pump can take 24V input and produce -12V output through the negative LDO. 
 You can try looking for charge pumps from this table: Selection Table for Inductorless (Charge Pump) DC/DC Converters | Parametric Search | Analog Devices 
 You can also look into LTM4655 which can operate within your desired specs: LTM4655 Datasheet and Product Info | Analog Devices)
