General Description
The MAX649/MAX651/MAX652 BiCMOS, step-down DC-DC switching controllers provide
high efficiency over three decades of load current. A unique, current-limited
pulse-frequency-modulated (PFM) control scheme gives these devices the
benefits of pulse-width-modulation (PWM) converters (high efficiency at heavy
loads), while using only 100µA of supply current (vs. 2mA to 10mA for PWM
converters). The result is high efficiency over loads ranging from 10mA to
more than 2.5A.
These devices use miniature external components. Their high switching
frequency (up to 300kHz) allows for less than 9mm diameter surface-mount
inductors.
The MAX649/MAX651/MAX652 have dropout voltages less than 1V and accept input
voltages up to 16.5V. Output voltages are preset at 5V (MAX649), 3.3V
(MAX651), and 3V (MAX652). These controllers can also be adjusted to any
voltage from 1.5V to the input voltage by using two resistors.
These step-down controllers drive external P-channel MOSFETs at loads greater
than 10W. If less power is required, use the MAX639/MAX640/MAX653 step-down
converters with on-chip FETs, which allow up to a 225mA load current.
