LM3269 Product details

Description

The LM3269 is buck-boost DC-DC converter designed to generate output voltages above or below a given input voltage and is particularly suitable for portable applications powered by a single-cell Li-ion battery.

Features

1 Operates From a Single Li-Ion Cell: 2.7 V to 5.5 V.
Adjustable Output Voltage: 0.6 V to 4.2 V.
Automatic PFM or PWM Mode Change.
750-mA Maximum Load Capability for VBATT ≥ 3 V, VOUT = 3.8 V.
2.4-MHz (typical) Switching Frequency.
Seamless Buck-Boost Mode Transition.
Fast Output Voltage Transition: 1.4 V to 3 V in 10 µs.
High-Efficiency: 95% typical at VBATT = 3.7 V, VOUT = 3.3 V, at 300 mA.
Input Overcurrent Limit.
