7MHz Switching Frequency Integrated Soft-Start Function Adjustable Output from VIN to 35V Low VCESAT Switch: 300mV at 1.
5A (Typical) 12V at 430mA from a 5V Input Small Thermally Enhanced 8-Lead MSOP Package U APPLICATIO S s s s s TFT-LCD Bias Supplies GPS Receivers DSL Modems Local Power Supply The LT®1946A is a fixed frequency step-up DC/DC converter containing an internal 1.
5A, 36V switch.
Capable of generating 12V at 430mA from a 5V input, the LT1946A is ideal for powering large TFT-LCD panels.
The LT1946A switches at 2.
7MHz, allowing the use of tiny, low profile inductors and low value ceramic capacitors.
Loop compensation can be either internal or external, giving the user flexibility in setting loop compensation and allowing optimized transient response with low ESR ceramic output capacitors.
Soft-start is controlled with an external capacitor w...
