LT1370

Complementing and expanding on the current LT1371/LT1372 family of 500kHz switchers, Linear Technology introduces the LT1370, a 6A boost converter. A high efficiency switch is included on the die, along with all the oscillator, control and protection circuitry necessary for a complete switching regulator. This part combines the convenience and low parts count of a monolithic solution with the switching capabilities of a discrete power device and controller. At 0.065Ω on-resistance, 42V maximum switch voltage and 500kHz switching frequency, the LT1370 can be used ...
