General Description
The RT5744 and RT5746 are step-down switching
voltage regulators that deliver a digitally programmable
output from an input voltage supply of 2.5V to 5.5V. The
output voltage is programmed through an I2C interface
that can operate up to 3.4MHz.
Using a proprietary architecture with synchronous
rectification, the RT5744 and RT5746 are capable of
delivering continuous 4A and 6A, maintaining that
efficiency at load currents as low as 10mA. The
regulator operates at a nominal fixed frequency of
2.4MHz, which reduces the external component counts.
Additional output capacitance can be added to improve
regulation during load transients without affecting
stability.
At moderate and light loads, Pulse Frequency
Modulation (PFM) is used to operate in power-saving
mode with a typical quiescent current of 45A at room
temperature. Even with such a low quiescent current,
the part exhibits excellent transient response during
large load swings. At higher loads, the system
automatically switches to fixed frequency control,
operating at 2.4MHz. In shutdown mode, the supply
current is typically 0.1A, and is excellent in reducing
power consumption. The PFM mode can be disabled if
the fixed frequency is desired. The RT5744 and RT5746
are available in WL-CSP-14B 1.31x2.02 (BSC) package.
The recommended junction temperature range is −40C
to 125C.
