High Efficiency, Boost Convertor with Programmable Current Limit

General Description

The LP6270 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 2.5A Current power MOSFET makes this converter highly power efficiently. The non-inverting input its error amplifier is connected to an internal 0.6V precision reference voltage. Soft-Start time can be programmed with an external capacitor, which sets the input current ramp rate. A built-in charge pump is used to drive the N-Channel MOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off. Its low quiescent current (16μA) and small package (TDFN-10) is particularly suitable in battery-powered portable equipment. Several protection functions include soft start to limit inrush current during plug-in, current limiting at 1500mA to meet USB power requirement, and thermal shutdown to protect damage under over current conditions.
