iC-DC Programmable Dual 2.5/3.3/5 V Buck/Boost SMPS
|
|
| Applications |
- Dual voltage supply by buck/boost converters with adjustable, back-end linear regulators
- Power management for laser, encoder, and automotive applications
|
|
| Features |
- Wide input voltage range of 4 to 36 V
- Reverse polarity protection up to -36 V with autarky function
- Universal buck/boost converter with high efficiency
- Two back-end, adjustable linear regulators (1.5 to 5.5 V) with a total of up to 300 mA of output current and a separate output voltage monitor
- Low residual ripple with small capacitors in the μF range
- Separate enable inputs for the linear regulators
- Two switched outputs referenced to the linear regulators
- Integrated switching transistors and flyback diodes
- Converter cut-off current can be set by an external resistor
- Integrated 3 MHz oscillator with no external components
- Active noise spectrum reduction
- Error messaging with overtemperature, overvoltage, and undervoltage at the current-limited open-collector output
- Wide temperature range of -40 to 125°C
- Protective circuitry against ESD
- QFN package requires little space and few external components
