NCP1500, Dual Mode PWM/Linear BUCK Converter
Pin # Symbol Pin Description 1 SHD Device is placed in shutdown when SHD is driven low.
In shutdown mode, the internal MOSFET and output are turned off.
Driven to high for normal operation.
This pin is floating internally and needs to be tied to a fixed source externally.

NCP1500 Dual Mode PWM/Linear BUCK Converter The NCP1500 is a dual mode converter that operates as either a pulse width modulated (PWM) buck converter or as a linear regulator.
The converter automatically transitions between the two modes.
The converter operates as a PWM when a synchronization signal is present at the sync input.
The converter operates as a linear regulator in the absence of a synchronization signal.
The PWM mode offers excellent performance at normal to heavy loads at the sacri
NCP1500 Features
* include thermal shutdown with hysteresis and cycle
* by
* cycle current limit in the PWM mode. Additionally, the converter transitions into PFM mode at very light loads if a synchronization signal is present and an output overvoltage condition is detected. PWM Features
* Current
