Description

The 5093MTC is a synchronous two-phase DC-DC controller IC which provides a highly accurate, programmable output voltage for VRM 9.x processors.

Two interleaved synchronous buck regulator phases with built-in current sharing operate 180° out of phase to provide the fast transient response needed to satisfy high current applications while minimizing external components.

The FAN5093 features Programmable Active Droop for transient response with minimum output capacitance. It has integrated high-current gate drivers, with adaptive delay gate switching, eliminating the need for external drive devices.

The FAN5093 uses a 5-bit D/A converter to program the output voltage from 1.10V to 1.85V in 25mV steps with an accuracy of 1%. The FAN5093 uses a high level of integration to deliver load currents in excess of 50A from a 12V source with minimal external circuitry.

Part Number: TPS50601-SP

Function: 1.6-V TO 6.3-V INPUT, 6A SYNCHRONOUS STEP DOWN SWIFT CONVERTER

Package: CFP 20, KGD Type

Manufacturer: Texas Instruments

Description

The TPS50301 is a 6.3-V, 3-A and the TPS50601-SP is a 6.3-V, 6-A synchronous step down converter which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs.

Further space savings are achieved through current mode control, which reduces component count, and a high switching frequency, reducing the inductor’s footprint. The devices are offered in a thermally enhanced 20-pin ceramic, dual in-line flatpack package.

Cycle-by-cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit which turns off the low-side MOSFET to prevent excessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature.

 

Features

1. Integrated 55-mΩ / 50-mΩ MOSFETs

2. Split Power Rail: 1.6 to 6.3 V on PVIN

3. Power Rail: 3 to 6.3 V on VIN

4. 6-A Maximum Output Current
