TC1313

500 mA Synchronous Buck Regulator,

+ 300 mA LDO

Features

Description

• Dual-Output Regulator (500 mA Buck Regulator

and 300 mA Low-Dropout Regulator (LDO))

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.

• Total Device Quiescent Current = 57 µA (Typical)

• Independent Shutdown for Buck and LDO

Outputs

• Both Outputs Internally Compensated

• Synchronous Buck Regulator:

- Over 90% Typical Efficiency

- 2.0 MHz Fixed-Frequency PWM

(Heavy Load)

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.

- Low Output Noise

- Automatic PWM-to-PFM mode transition

- Adjustable (0.8V to 4.5V) and Standard

Fixed-Output Voltages (0.8V, 1.2V, 1.5V,

1.8V, 2.5V, 3.3V)

• Low-Dropout Regulator:

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.

- Low-Dropout Voltage = 137 mV Typical @

200 mA

- Standard Fixed-Output Voltages

(1.5V, 1.8V, 2.5V, 3.3V)

• Small 10-pin 3x3 DFN or MSOP Package Options

• Operating Junction Temperature Range:

- -40°C to +125°C

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.

• Undervoltage Lockout (UVLO)

• Output Short Circuit Protection

• Overtemperature Protection
