LP6250 Product details

General Description
The LP6250 is high efficiency Synchronous Boost
DC/DC Converter, fixed frequency, current-mode
step-up converter with output to input disconnect. A
PWM step-up DC/DC converters optimized to
provide a high efficiency solution to medium power
system. Its PWM circuitry with built-in
2.1A@250mΩ power mosfet makes this converter
highly power efficiently. Selectable high switching
frequency allows faster loop response and easy
filtering with a low noise output. The non-inverting
input its error amplifier is connected to an internal
0.5V precision reference voltage. Soft-start time can
be programmed with an external capacitor, which
sets the input current ramp rate. Current mode
control and external compensation network make it
easy and flexible to stabilize the system. the devices
regulates the output voltage up to 5V from either a
2cell NiMH/NiCd or a single-cell Li-ion Battery
with a 500KHz fixed frequency switching. These
features minimize overall solution footprint by
allowing the use of tiny, low profile inductors and
ceramic capacitors.

Features
‹ Up to 94% efficiency 
‹ Shut-down current:<1uA  
‹ Output voltage Up to 5V
‹ 500KHz fixed frequency switching
‹ High switch on current:2.1A@250mΩ
‹ Available in TDFN-10 Package

Applications
-Battery products
-Host Products
-Motor Power Devices
