Description: High-Efficiency / PWM / Step-Down DC-DC Controllers in 16-Pin QSOP

Features

* o 96% Efficiency o Small, 16-Pin QSOP Package (half the size of a 16-pin narrow SO) o Pin-Compatible with MAX797 (MAX1653/MAX1655) o Output Voltage Down to 1V (MAX1655) o 4.5V to 30V Input Range o 99% Duty Cycle for Lower Dropout o 170µA Quiescent Supply Current o 3µA Logic-Controlled Shutdown o Dua

Applications

* All devices operate with a selectable 150kHz/300kHz switching frequency, which can also be synchronized to an external clock signal. Both external power switches are inexpensive N-channel MOSFETs, which provide low resistance while saving space and reducing cost. The MAX1652 and MAX1654 have an add
