RT6296F Datasheet, PDF (1/12 Pages) Richtek Technology Corporation – The RT6296F is a high-efficiency
RT6296F
2A, 17V Current Mode Synchronous Step-Down Converter
General Description
The RT6296F is a high-efficiency, 2A current mode
synchronous step-down DC/DC converter with a wide
input voltage range from 4.5V to 17V. The device
integrates 100m high-side and 40m low-side
MOSFETs to achieve high efficiency conversion. The
current mode control architecture supports fast
transient response and internal compensation. A
cycle-by-cycle current limit function provides protection
against shorted output. The RT6296F provides
complete protection functions such as input
under-voltage lockout, output under-voltage protection,
over-current protection, and thermal shutdown. The
PWM frequency is adjustable by the EN/SYNC pin. The
RT6296F is available in the TSOT-23-8 (FC) package.
