Description

The TPS544B20 and TPS544C20 devices are PMBus compatible, non-isolated DC-DC Integrated
FET converters, capable of high-frequency operation and delivering 20-A , or 30-A current output from a 5 mm × 7 mm package, enabling high-power density and fast transient performance with minimal PCB area.

The PMBus interface provides for converter configuration as well as monitoring of key parameters including output voltage, current and an optional external temperature. High-frequency, low-loss switching, provided by an integrated NexFET power stage and optimized drivers, allows for very high-density power solutions and reduced inductor and filter capacitor sizes. Response to fault conditions can be set to either restart or latch off depending on system requirements.

Features

1. Single Thermal Pad

2. Integrated 4.5-mΩ and 2.0-mΩ Stacked NexFET Power Stage

3. 600-mV, 0.5% Reference

4. Lossless, Low-Side MOSFET Current Sensing

5. Selectable D-CAP and D-CAP2 Mode Control

6. Differential Remote Sensing

7. Monotonic Start-Up into Pre-Biased Output

Description

The SS6610, SS6611 are high-efficiency step-up DC/DC converters, with a start-up voltage aslow as 0.8V, and an operating voltage down to 0.7V. Consuming only 20µA of  quiescent current, these devices include a built-in synchronous rectifier that reduces size and cost by eliminating the need for an external Schottky diode, and improves overall efficiency by minimizing losses.

Features

1. High efficiency. (93% when VIN=2.4V, VOUT=3.3V, IOUT=200mA)
2. Output current up to 500mA. (SS6610 at VIN=2.4V and VOUT=3.3V)
3. Quiescent supply current of 20mA.
4. Power-saving shutdown mode (0.1μA typical).
5. Internal synchronous rectifier (no external diode required).
6. On-chip low-battery detector.
7. Low battery hysteresis

Applications

1. Palmtop & Notebook Computers.
2. PDAs
3. Wireless Phones
4. Pocket Organizers.
5. Digital Cameras
