LT1946AEMS8E#PBF Datasheet PDF - Linear Technology

●The LT1946AEMS8E#PBF is a fixed-frequency step-up DC-to-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 which determines the input current ramp rate during start up. The high switching frequency ensure a low profile overall solution less than 1.1mm high.

● Integrated soft-start function

● Adjustable output from VIN to 35V

● 300mV at 1.5A Typical low VCESAT switch

● 12V at 430mA from a 5V Input
