LTC3862 Datasheet - Linear Technology

LTC3862 Step-Up DC/DC Controller

The LTC®3862 is a two phase constant frequency, current mode boost and SEPIC controller that drives N-channel power MOSFETs. Two phase operation reduces system filtering capacitance and inductance requirements. The operating frequency can be set with an external resistor over a 75kHz to 500kHz rang.
