Step-up DC/DC converter uses fixed-frequency current-mode control and includes an integrated Schottky rectifier. The converter operates from a 2.5 V to 16 V input range and supports boost outputs up to 38 V. The LT3461 switching frequency is 1.3 MHz, and the high-voltage switch is rated for 40 V with a 300 mA minimum current limit. The device is supplied in a low-profile 6-lead TSOT-23 ThinSOT package and is specified for operation from -40 °C to 85 °C by design and characterization.
