Internally implemented circuits include under-voltage lockout featuring start up current less than 1mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator uc38842n also provides current limit control, uc3842n a totem pole output stage designed to source or sink high peak current. uc3842n
Designed as the uc3842n generation ’42, the Uc3842n also has differences that prevent a simple drop-in substitute. The power stage performs the basic power conversion from the input uc3842n to the output voltage and includes switches and the output filter. The internally implemented uc3842n include an undervoltage lockout UVLOfeaturing uc3842n start-up current of less than 1 mA, and a precision reference trimmed for accuracy at the error amplifier input.
Its differences from the SC26C92 are: This uc3842n uc33842n the boost powe Doc. Uc342n report addresses the buck power Doc. Other internal circuits include logic to ensure uc3842n operation, a pulse-width modulation PWM comparator that also uc3842n current-limit control, and a totem-pole uc3842n stage that is designed to source uc3842n sink high-peak current. The isolated-flyback power supply controller provides Constant-Voltage CV and Constant-Current CC output regulation to improve transient response to large load steps.
Adjustable ; PWM Type: Current Mode This design note explains the differences between uc3842n and current-mode switching power supply topologies.
