October 22, 2009[Ideas For Design] Simple Circuit Provides Latching Fault Protection
Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant circuitry. For power-supply controllers with an external soft-start pin, however, a simple circuit can be added to convert its non-latching fault protection into one with latched protection. For typical controllers, the startup sequence begins by charging the VDD...
July 7, 2005[Ideas For Design] Bootstrapping Provides Power-Supply Startup Sequencing
In multiple-output-voltage power supplies, the topology may place restrictions on the startup sequence. This can be particularly troublesome in an isolated power supply, where a lower output voltage must be present before a higher output voltage. Typically, the higher voltage is the source of power for the lower voltage output. Consider a system with an isolated 48-V input supply with a 3.3-V/9-A output and a 1.8-V/3-A output. The 1.8-V output must be present at the load before the...
