Configure buck converter for boost operation - 12/17/98 Issue of
EDN Buck converters are inherently different from boost converters,
because buck converters typically use the high side of the output as...

Constant-on-time buck-boost regulator converts a positive input to a
negative output - 7-Dec-04 Issue of EDN Buck regulators find
wide application as step-down regulators for converting large positive input
voltages into a smaller positive output voltages. Figure 1 shows a
simplified buck regulator that operates in continuous-conduction mode—that
is, the inductor current always remains positive..... [Design Idea by Robert
Bell, National Semiconductor Inc, Chandler, AZ] |

Get buck-boost performance from a boost regulator - 11-Jul-02 Issue of EDN
The SEPIC (single-ended, primary-inductance-converter] topology is generally a good
choice for voltage regulators that must produce an on output voltage that falls in the
middle of the input-voltage range, such as a 5V output from a 2.7 to 6V input, The
topology has some disadvantages, however. The efficiency of a SEPIC circuit fares
worse than that of buck and boost regulators, and SEPIC desig.... [Design Idea by Tom

Step up/step-down current-source charges batteries - 6-Jun-96 Issue of EDN
For battery charging, the highly efficient step-down (buck] configuration is usually
the topology of choice. However, a different approach is necessary if the following
conditions prevail The supply voltage is less than the battery voltage, or, even
worse, the supply voltage ranges above and below the battery voltage.... [Design Idea

Synchronous OCM Buck-Boost - This reference design is synchronous Buck/Boost
converter that can deliver up to 3.8 A of continuous current at -5 V from a 5 V input.
This topology uses a synchronous buck controller (TPS5103) referenced to the negative
output rail. The synchronous MOSFETs allow this design to achieve a peak efficiency of
88%. In addition, the TPS5103 provides a soft-start function and over-current
protection. (added 3/05) |
