YB1421 1.5A Boost Regulator

High Efficiency 1MHz, 1.5A Boost Regulator YB1421 Series INTRODUCTION: The YB1421 is designed for single-cell or dual-cell or triangle-cell alkaline, NiMH, or NiCd or single-cell lithium-ion battery powered application. It is a high efficiency boost converter with 600mV feedback voltage. switching frequency of 1.0MHz minimizes solution footprint by allowing the use of tiny low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, and the dev.
