High Efficiency, Boost Convertor with Programmable Current Limit

General Description

converter. Its PWM circuitry with built-in 2.6A 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 (QFN-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.
