Features

* a power-saving discontinuous operating mode at light loads. The recommended junction temperature range is
* 40C to 125C and ambient temperature range is
* 40C to 85C. 2 Features
* Fast Transient Response
* Steady 650kHz Switching Frequency at all Load Current (RT2859B)

Applications

* especially for low output voltages and low duty cycles. Cycle-by-cycle current limit, input under-voltage lockout, externally-adjustable soft-start, output underand over-voltage protection, and thermal shutdown provide safe and smooth operation in all operating conditions.
