Features
1. Compact Size: Available in a small SOT-23 package, making it suitable for space-constrained applications.
2. Efficiency: Offers high efficiency, often greater than 80%, due to its internal 1A, 36V switch.
3. Wide Input Voltage Range: Operates from a 2V to 16V input voltage range, suitable for single or multi-cell battery-powered devices.
4. High Output Voltage: Capable of generating output voltages up to 34V.
5. Low Quiescent Current: Features a low quiescent current of 20µA, minimizing power consumption during standby.
6. Current Mode Control: Provides excellent line and load regulation as well as dynamic response.
7. Fast Switching Frequency: Operates at 1.2MHz, allowing the use of small, low-cost inductors and capacitors.
8. Protection Features: Includes features like soft-start and thermal shutdown to protect the device from damage.
These features make the LT1930ES5#TRPBF suitable for applications such as LED drivers, OLED power supplies, and other portable electronics requiring efficient boost regulation.
Pinout
1. SW (Pin 1): This is the switch pin where the inductor is connected. It handles the switching to step-up the voltage.
2. GND (Pin 2): Ground pin, which is the reference point for the circuit.
3. FB (Pin 3): Feedback pin used to set the output voltage via an external resistor divider network.
4. SHDN (Pin 4): Shutdown pin, which is used to turn the converter on or off. When low, the device is in shutdown mode; when high, it is operating.
5. VIN (Pin 5): Input voltage pin where the supply voltage is connected.
These pin assignments allow the LT1930 to efficiently boost the input voltage to a higher output voltage, making it suitable for applications requiring a compact form factor and efficient power conversion.
