GL2595L
2A STEP-DOWN VOLTAGE SWITCHING REGULATORS
Description
The GL2595L series are monolithic IC designed for a step-
down DC/DC converter, and own the ability of driving a 2A
load without additional transistor. It saves board space. The
external shutdown function can be controlled by logic level
and then come into standby mode. The internal compensa-
tion makes feedback control have good line and load regu-
lation without external design. Regarding protected func-
tion, thermal shutdown is to prevent over temperature oper-
ating from damage, and current limit is to prevent over cur-
rent operating of the output switch. If current limit function
occurred and Vfb is down to 0.5V below, the switching fre-
quency will be reduced. The GL2595L series operate at a
switching frequency of 150 KHz thus allowing smaller sized
filter components than what would be needed with lower fre-
quency switching regulators. Other features include a guar-
anteed ±4% tolerance on output voltage under specified in-
put voltage and output load conditions, and ±15% on the os-
cillator frequency. The output version included fixed 3.3V,
5V, 12V, and an adjustable type. The chips are available in
a standard 8-lead SOP8F package.
