Description

The

TC1303/TC1304

combines

500 mA

synchronous buck regulator and 300 mA Low-Dropout

Regulator (LDO) with a power-good monitor 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.

For the TC1303/TC1304, the power-good output is

based on the regulation of the buck regulator output, the

LDO output or the combination of both. The TC1304

features start-up and shutdown output sequencing.

The TC1303/TC1304 is available in either the 10-pin

DFN or MSOP package.

Additional protection features include: UVLO,

overtemperature and overcurrent protection on both

outputs.
