The LTC3256EMSE#PBF is a wide VIN range dual output 350mA step-down charge pump with watchdog timer in 16 pin MSOP package. This switched capacitor step-down DC to DC converter produces two regulated outputs (5V output via direct connection to the charge pump output and 3.3V output via a low dropout (LDO) linear post regulator). The device provides up to 350mA of total output current. At 12V VIN and maximum load on both outputs, power dissipation is reduced by over 2W compared to a dual LDO regulator solution. The LTC3256 maximizes efficiency by running charge pump in 2: 1 mode over as wide an operating range as possible and automatically switches to 1: 1 mode as needed due to VIN and load conditions. An integrated watchdog timer, independent power good outputs and reset input ensure reliable system operation and fault monitoring. A buffered 1.1V reference output enables system self testing for safety critical applications.

• Input voltage range from 5.5V to 38V
• 5V output (100mA maximum) and 3.3V LDO output (250mA maximum)
• Multimode step-down charge pump (2: 1, 1: 1) with automatic mode switching
• Low quiescent current of 20µA with both outputs regulating (no load) & 0.5µA in shutdown
• Engineered for diagnostic coverage in ISO26262 systems
• 1.1V reference output for system diagnostics
• Power-on reset and watchdog controller with adjustable timing
• Overcurrent fault protection, overtemperature protection and tolerance of 38V input transients
• Controlled input current and switching slew rates minimize conducted and radiated EMI
• Operating temperature range from -40°C to 125°C
