LTC3559  
Linear USB Battery Charger  
with Dual Buck Regulators  
FEATURES  
DESCRIPTION  
The LTC®3559 is a USB battery charger with dual high ef-  
ficiencybuckregulators.Thepartisideallysuitedtopower  
single cell Li-Ion/Polymer based handheld applications  
needing multiple supply rails.  
Battery Charger  
■
Standalone USB Charger  
■
Up to 950mA Charge Current Programmable via  
Single Resistor  
■
HPWR Input Selects 20% or 100% of Programmed  
Battery charge current is programmed via the PROG pin  
and the HPWR pin, with capability up to 950mA at the BAT  
pin. The battery charger has an NTC input for temperature  
qualified charging. The CHRG pin allows battery status to  
be monitored continuously during the charging process.  
An internal timer controls charger termination.

CHRG indicates C/10 or Timeout  
Buck Regulators  
Each monolithic synchronous buck regulator provides up  
to 400mA of output current while operating at efficiencies  
greater than 90% over the entire Li-Ion/Polymer range.  
A MODE pin provides the flexibility to place both buck  
regulators in a power saving Burst Mode operation or a  
low noise pulse skip mode.
