Natural Interleaving™ Transition-Mode PFC Controller With Improved

Audible Noise ImmunityUCC28063

•Two-Phase natural 180º interleaving Transition-mode operation•Phase management capability•Brown out, open loop detection, peak current limiting during in-rush and other protection features•No reverse recovery losses in diodes•Two-Power stage architecture•Fail-Safe OVP so that any single failure does not allow the output to failure does not allow the output to boost above safe levels.

•200-W to 800-W Power Supplies•Gaming•D-to-A Set-Top Boxes•Adapters•LCD, Plasma and DLP™ TVs•Home Audio Systems

•Input filter and output ripple current cancellation, leading to physical size

reduction of EMI and bulk storage capacitor. Lower system cost and less complex

design than continuous conduction mode (CCM) controllers.

•Allows a phase to be shut down at light loads making the PFC stage more

efficient by eliminating MOSFET switching losses of that phase, making it ideal

for Energy Star and 80 Plus power supply requirements.

•Brings a higher level of robustness and reliability to the application.

•Lower cost diodes can be used instead of 600V silicon carbide rectifiers

•More effectively spreads heat dissipation from power stage elements such as

diodes, inductors and MOSFETS.

•Redundant output OVP, monitored by VSENSE and HVSEN pins. PWM shuts

down if either exceeds the over voltage threshold.

Understanding Low IQIQ is needed by the internal circuits of the LDO to increase the performance of

certain parameters, PSRR, Noise, transients, etc... Therefore it is a tradeoff to have

very low IQ vs. higher performance. Typically the main reason for using an ultra low

IQ LDO is battery life or because the LDO spends a lot of time in the no load or off

state.

Typical applications that benefit from

these types of LDOs•Capacitive Touch

•Wireless •Wireless

•Utility Metering

•Portable Medical and Instrumentation

•Security & Safety

•Energy Harvesting

•USB

•Keep Alive

Understanding the Bias Voltage Input

The Bias input of the LDO provides the higher voltage necessary for the

control and performance circuitry. The lower voltage on the pass FET

input allows for lower power loss.

Traditional LDO

(3.3V to 0.8V)

LDO with Bias Input

(1.1V to 0.8V)

84% reduction in

power loss!

P = 875 mW(3.3-0.8)x350

P = 140 mW(1.2-0.8)x350

Allows very low input voltages in power path for efficient conversions.

Provides very high PSRR and excellent transient response.

High PSRR

PSRR is the ability to reject/filter noise from the input power to the output voltage. The higher the PSRR,

expressed in dB) of the LDO, the better it is at filtering the noise from the input supply.

• A Switching power supply’s noise can be cleaned up to increase performance of application.

• High frequency noise can affect audio, VCOs, camera sensors, RF transmitters, etc…

• LDOs won’t affect loop stability as would adding an LC filter to try and have the same effect.

Fast Transient Response

• The transient response of an

LDO is the ability to control

the output voltage while a

change in either input voltage

or load is occuring.

• The faster the transient event,

the more difficult it is for the

the more difficult it is for the
