NCP1530DM27R2 شرح
NCP1530
600 mA PWM/PFM
Step−Down Converter with
External Synchronization Pin
The NCP1530 is a PWM/PFM non−synchronous step−down
(Buck) DC−DC converter for usage in systems supplied from 1−cell
Li−ion, or 2 or more cells Alkaline/NiCd/NiMH batteries. It can
operate in Constant−Frequency PWM mode or PWM/PFM mode in
which the controller will automatically switch to PFM mode
operation at low output loads to maintain high efficiency. The
switching frequency can also be synchronized to external clock
between 600 kHz and 1.2 MHz. The maximum output current is up
to 600 mA. Applying an external synchronizing signal to SYN pin
can supersede the PFM operation.
The NCP1530 consumes only 47 mA (typ) of supply current
(VOUT = 3.0 V, no switching) and can be forced to shutdown mode by
bringing the enable input (EN) low. In shutdown mode, the regulator
is disabled and the shutdown supply current is reduced to
0.5 mA (typ). Other features include built−in undervoltage lockout,
internal thermal shutdown, an externally programmable soft−start
time and output current limit protection. The NCP1530 operates
from a maximum input voltage of 5.0 V and is available in a space
saving, low profile Micro8package.
