Overview
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...
