LTC3672BEDC-1

The LTC3672BEDC-1 is a low-noise and dual-output, low-dropout linear regulator, high-frequency, synchronous buck switching voltage regulator, ideal for powering digital and analog load in applications including telecommunications, tablet PCs, laptop PCs and other equipment. It is part of the PMIC—Voltage Regulators—Linear + Switching family of products.

Its features include:

• Dual output voltage
• Low-dropout output linear regulator
• High frequency, synchronous buck (only LTC3672BEDC) regulator
• High-efficiency, low-noise operation
• Wide Ohmic output current
• 65µs overshoot transient response
• Slope compensation for improved transient response
• Over-current protection and thermal overload shutdown.

The LTC3672BEDC-1 can be used in a wide variety of applications in the telecommunications, tablet and laptop computer markets. Used in combination with an external MOSFET and inductor, the LTC3672BEDC-1 can generate two regulated outputs over a wide input voltage range. It operates at low noise and is capable of high efficiency operation. It also features an integrated thermal shutdown circuit which helps protect both the regulator and load devices.

The LTC3672BEDC-1 works on a principle known as the coupled-inductor multiple-output converter. This regulator utilizes two inductors: one connected to the input and one connected to the output. When the switch is activated, the current from the input inductor is transferred to the output inductor. The two inductors are coupled so that a voltage is developed across the inductors, allowing for efficient energy transfer from the input to the output. The regulator also contains current-sense resistors, allowing for proper current-limit operation and over-current protection.

The LTC3672BEDC-1 also features a slew-rate control circuit. This circuit allows for a smooth transition of the output voltage, which results in low overshoot and better performance during load transients. The slew-rate control circuit is also useful in applications where noise immunity is required.

Overall, the LTC3672BEDC-1 is an ideal choice for powering digital and analog loads in telecommunications, tablet PCs, laptop PCs and other equipment. This device has built-in over-current protection and thermal shutdown circuits for added safety, and its high-frequency, synchronous buck regulator can achieve high efficiency with low noise operation. With its wide output current range, low-dropout linear regulator, and improved transient response due to its slope-compensation circuit, the LTC3672BEDC-1 is the perfect choice for applications requiring reliable and efficient power supply.
