3 Description
The TLV62565/6 devices are synchronous step-down
converters optimized for small solution size and high
efficiency. The devices integrate switches capable of
delivering an output current up to 1.5 A.
The devices are based on an adaptive on time with
valley current mode control scheme. Typical
operating frequency is 1.5 MHz at medium to heavy
loads. The devices are optimized to achieve very low
output voltage ripple even with small external
components and feature an excellent load transient
response.
During light load, the TLV62565/6 automatically enter
into Power Save Mode at the lowest quiescent
current (50 μA typ) to maintain high efficiency over
the entire load current range. In shutdown, the
current consumption is reduced to less than 1 μA.
The TLV62565/6 provide an adjustable output voltage
via an external resistor divider. The output voltage
start-up ramp is controlled by an internal soft start,
typically 250 μs. Power sequencing is possible by
configuring the Enable (TLV62565) and Power Good
(TLV62566) pins. Other features like over current
protection and over temperature protection are builtin.
The TLV62565/6 devices are available in a SOT-
23 5-pin package.
