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  
1
(V  
= 3.0 V, no switching) and can be forced to shutdown mode by  
OUT  
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 Micro8 package.
