Product Overview
LTC3442 is a highly efficient, fixed frequency, buck boost DC/DC converter, which operates from input voltages above, below, and equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for a single lithium-ion or multicell alkaline applications where the output voltage is within the battery voltage range. The device includes two 0.10 ohm N-channel MOSFET switches and two 0.10 ohm P-channel switches. Operating frequency and average input current limit can each be programmed with an external resistor. Automatic Burst Mode operation allows the user to program the load current for Burst Mode operation, or to control it manually. It is used in application such as PDA/'SMART' phones, handheld computers, MP3 players, handheld instruments, digital cameras, wireless handsets, USB peripherals etc.
- Regulated output with input voltages above, below, or equal to the output
- Single inductor, no schottky diodes required
- Manual or programmable automatic Burst Mode® operation
