G5177ARE1U同步 整流升压变换器-GMT

General Description
The G5177A is a compact, high-efficiency, synchro-
nous step-up converter with power Mosfets embedded
and with output shutdown and adjustable output cur-
rent limiting with foldback for a single-cell
Li-ion/polymer battery. The G5177A uses only 50μA
(typ) quiescent current and allows the converter to
switch only when needed at no load and light loads,
and when load is higher than 100mA， it uses
fixed-frequency PWM technique at 1MHz. It features a
current mode control for fast transient response with
intemal compensation. The G5177A includes cy-
cle- by- cycle current limit to maximum inductor current
and over-temperature protection circuit. The G5177A
is suitable for iPad-like computers, smart phones and
portable handheld devices.
The G5177A is available in a 3mm X 3mm TDFN
package. The operating temperature range is from
-45°C to +85°C.
