Multi-output, Low-noise Power Supply Controller For Notebook Computers

The SC1402 is pin compatible with the MAX1632 with improved load regulation performance. The SC1402 is a multiple-output power supply controller designed to power Logic supply components in battery operated systems. The SC1402 utilizes synchronous rectified buck topologies to generate two voltages, (3.3V and 5V) with up to 95% efficiency. It also provides two lin- ear Regulators for system housekeeping functions. The 12V linear Regulator output is generated from a coupled inductor of the 5V Switching Regulator Control functions include: power up sequencing, soft start, power-good signaling, Automatic bootstrapping for high side MOSFETs and frequency synchroniza- tion. An internal precision 2.5V reference ensures 2% output voltage. The internal Oscillator CAN be adjusted to 200kHz, 300kHz or synchronized to an external Clock The MOSFET drivers provide 1A peak drive current for fast MOSFET switching. The SC1402 includes a PSAVE enable input to select a pulse skipping mode for high efficiency or a fixed fre- quency mode for low noise operation. By Semtech Corporation
