Description
The TC1313 device combines a 500 mA synchronous
buck regulator and 300 mA Low-Dropout Regulator
(LDO) to provide a highly integrated solution for
devices that require multiple supply voltages. The
unique combination of an integrated buck switching
regulator and low-dropout linear regulator provides the
lowest system cost for dual-output voltage applications
that require one lower processor core voltage and one
higher bias voltage.
The 500 mA synchronous buck regulator switches at a
fixed frequency of 2.0 MHz when the load is heavy,
providing a low-noise, small-size solution. When the
load on the buck output is reduced to light levels, it
changes operation to a Pulse Frequency Modulation
(PFM) mode to minimize quiescent current draw from
the battery. No intervention is necessary for smooth
transition from one mode to another.
The LDO provides a 300 mA auxiliary output that
requires a single 1 µF ceramic output capacitor,
minimizing board area and cost. The typical dropout
voltage for the LDO output is 137 mV for a 200 mA
load.
The TC1313 device is available in either the 10-pin DFN
or MSOP package.
Additional
protection
features
include:
UVLO,
overtemperature and overcurrent protection on both
outputs.
