LTC3612MPFE#TRPBF is a low noise, high performance synchronous step-down switching regulator. It is designed for use in applications including point-of-load (POL) power supplies, battery chargers, as well as other high efficiency, space-constrained applications that require high efficiency and low heat dissipation. It is widely used in communications, industrial, automotive, and consumer electronic applications.

The LTC3612MPFE#TRPBF is part of the ultra-small package family of DC-DC switching regulators offered by Linear Technology. It is a 2-phase non-synchronous buck regulator in a 4mm x 4mm x 0.75 mm TSSOP-16 package, making it ideal for high density applications. The device operates from a wide range to an adjustable output voltage from 0.6 V to 0.85 V. It provides up to 2A of current at no load and up to 1.5A at full load. It has a switching frequency of 700 kHz and a programmable soft start circuit.

The LTC3612MPFE#TRPBF is a non-synchronous step-down switching regulator that uses a current-mode control (CMC) architecture to provide high efficiency, low noise, and fast transient response. The CMC architecture enables the use of an external loop compensation device to maximize the loop bandwidth and minimize the effects of supply and load transients. The device has a master-slave control architecture that operates two power stages with two independent switching signals, optimized to minimize the ripple current associated with non-synchronous operation.

The LTC3612MPFE#TRPBF uses a programmable soft-start circuit to reduce inrush current during start-up and enable the device to achieve stable output voltages quickly and without any transient overshoot. It has an active current-sharing circuit, which allows two-phase operation and increases the maximum load current capability of the device up to twice the rated current. Pulling the SD pin low puts the device into shutdown mode, reducing the quiescent current of the device to less than 5 µA.

The LTC3612MPFE#TRPBF provides excellent power efficiency, up to 95%, thereby dissipating less heat and lowering component count. It offers short-circuit protection and integrated under-voltage lockout (UVLO). It is suitable for operation from a wide range of supply voltages, including 12V, 18V and 24V.

In summary, the LTC3612MPFE#TRPBF is a high performance, low noise, low component count synchronous step-down switching regulator suitable for a wide range of high-efficiency, space-constrained applications. Its small footprint and excellent power efficiency make it an ideal choice for point-of-load (POL) power supplies, battery chargers, and other power-constrained applications. With its advanced features, it is well-suited for communications, industrial, automotive, and consumer electronic applications.
