LTC3458EDE#PBF

LTC3458 is a high efficiency, current mode, fixed frequency, step up DC/DC converter with true output disconnect and inrush current limiting. It is rated for a 7.5V output and includes a 0.3 ohm N-channel MOSFET switch and a 0.4 ohm P-channel MOSFET synchronous rectifier. It is well suited for battery powered applications and includes programmable output voltage, switching frequency and loop compensation. The Burst Mode current threshold, peak current limit, and soft start are externally programmable. It is widely used in application such as point-of-load regulators, USB VBUS power, LCD bias, OLED displays etc.
