500 mA PFM Step-Up DC-DC Controller CN5136
General Description
CN5136 is a high-efficiency pulse frequency modulation (PFM) DC-DC converter, and the maximum output current capability is up to 500mA.
CN5136 has an on-chip power
transistor, thus greatly reduces the external component count.
Other features include the maximum inductor current limit, soft-start circuit.
CN5136 output voltage can be set by external resistors.
High accuracy on-chip voltage reference ensures the accuracy of the output voltage and low temperature drift.
CN5136 can operate from the voltage of 2.
7V to 6V, which is very suitable for lithium and three nickel-metal hydride battery-powered applications.
