LTC3407IDD-2#PBF

LTC3407-2 is a dual, constant-frequency, synchronous step down DC/DC converter. Intended for low power applications, it operates from 2.5V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, allowing the use of tiny, low cost capacitors and inductors with a profile ≤1.2mm. A user selectable mode input is provided to allow the user to trade-off noise ripple for low power efficiency. Burst Mode® operation provides high efficiency at light loads, while pulse-skipping mode provides low noise ripple at light loads. It is widely used in application such as PDAs/palmtop PCs, digital cameras, cellular phones, portable media players, PC cards, wireless and DSL modems etc.

• High efficiency upto 95%
• Very low quiescent current is 40µA typical
• Peak switch current limit is 1.2A typical
• No schottky diodes required, low RDS(ON) internal switch is 0.35 ohm
• Current mode operation for excellent line and load transient response
• Short-circuit protected, low dropout operation is 100% duty cycle
• Ultralow shutdown current is <lt/> 1µA maximum
• Power-on reset output, externally synchronizable oscillator
• Operating temperature is -40°C to 125°C
• Packaging style is 10-lead plastic DFN
