DESCRIPTION
The LTC®3569 contains three monolithic, synchronous step-down DC/DC converters. Intended for medium power applications, it operates over a 2.5V to 5.5V input voltage range. The operating frequency is adjustable from 1MHz to 3MHz, allowing the use of tiny, low cost capacitors and inductors. The three output voltages are independently programmable by toggling the EN pins up to 15 times, lowering the 800mV FB references by 25mV per cycle. The first buck regulator sources load currents up to 1200mA. The other two buck regulators each provide 600mA.
FEATURES
■ Three Independent Current Mode Buck DC/DC
Regulators (1.2A and 2 × 600mA)
■ Single Pin Programmable VFB Servo Voltages from
800mV Down to 425mV (in 25mV Steps)
■ Pull VFB High to Make Each 600mA Buck a Slave for
Higher Current Operation
■ Pulse-Skipping or Burst Mode® Operation
■ Programmable Switching Frequency
(1MHz to 3MHz) or Fixed 2.25MHz
■ Synchronizable (1.2MHz to 3MHz)
■ VIN Range 2.5V to 5.5V
■ All Regulators Internally Compensated
■ PGOOD Output Flag
■ Quiescent Current <100µA (All Regulators in Burst
Mode Operation)
■ Zero Shutdown Current
■ Overtemperature and Short-Circuit Protection
■ Tiny 3mm × 3mm, 3mm × 4mm 20-Lead QFN and
Thermally Enhanced TSSOP FE-16 Packages
APPLICATIONS
■ Portable Applications with Multiple Supply Rails
■ General Purpose Step-Down DC/DC
■ Dynamic Voltage Scaling Applications
