FEATURES  
DESCRIPTIO  
TheLTC®1159seriesisafamilyofsynchronousstep-down  
switching regulator controllers featuring automatic Burst

Available in SSOP and SO Packages  
A separate pin and on-board switch allow the MOSFET  
driver power to be derived from the regulated output  
voltageprovidingsignificantefficiencyimprovementwhen  
operating at high input voltages. The constant off-time  
current-mode architecture maintains constant ripple cur-  
rent in the inductor and provides excellent line and load  
transient response. The output current level is user pro-  
grammable via an external current sense resistor.

APPLICATIO S  
■
Step-Down and Inverting Regulators  
The LTC1159 automatically switches to power saving  
Burst Mode operation when load current drops below  
approximately 15% of maximum current. Standby current  
is only 300µA while still regulating the output and shut-  
down current is a low 20µA.
