2 MHz / 3 MHz Ultra Small Step Down Converter in 1x1.5 SON Package

FEATURES

DESCRIPTION

• 2 MHz / 3 MHz Switch Frequency

The TPS6223X device family is a high frequency

• Up to 94% Efficiency

synchronous step down DC-DC converter optimized

• Output Peak Current up to 500mA

for battery powered portable applications. It supports

up to 500mA output current and allows the use of tiny

• Excellent AC and Transient Load Regulation

and low cost chip inductors and capacitors.

• High PSRR (up to 90dB)

With a wide input voltage range of 2.05V to 6V the

• Small External Output Filter Components 1μH/

device supports applications powered by Li-Ion

4.7μF

batteries with extended voltage range. The minimum

• V

range from 2.05V to 6V

input voltage of 2.05V allows as well the operation

• Optimized Power Save Mode For Low Output

from Li-primary or two alkaline batteries. Different

Ripple Voltage

fixed output voltage versions are available from 1.0V

to 3.3V.

• Forced PWM Mode Operation

The TPS6223X series features switch frequency up

• Typ. 22 μA Quiescent Current

to 3.8MHz. At medium to heavy loads, the converter

• 100% Duty Cycle for Lowest Dropout

operates in PWM mode and automatically enters

• Small 1 × 1.5 × 0.6mm

SON Package

Power Save Mode operation at light load currents to

• 12 mm

Minimum Solution Size

maintain high efficiency over the entire load current

range.

• Supports 0.6 mm Maximum Solution Height

Because of its excellent PSRR and AC load

• Soft Start with typ. 100μs Start Up Time

regulation performance, the device is also suitable to

replace linear regulators to obtain better power

APPLICATIONS

conversion efficiency.

• LDO Replacement

The Power Save Mode in TPS6223X reduces the

• Portable Audio, Portable Media

quiescent current consumption down to 22μA during

• Cell Phones

light load operation. It is optimized to achieve very

low output voltage ripple even with small external

• Low Power Wireless

component and features excellent ac load regulation.

• Low Power DSP Core Supply

For very noise sensitive applications, the device can

• Digital Cameras

be forced to PWM Mode operation over the entire

load range by pulling the MODE pin high. In the

shutdown mode, the current consumption is reduced

to less than 1μA. The TPS6223X is available in a 1 ×

1.5mm

6 pin SON package.
