WD1012EA-5/TR
1.
5MHz, 600mA Synchronous Step-Down
Regulator in SOT
General Description
The WD1012EA is a high efficiency monolithic synchronous buck
regulator using a constant frequency, current mode architecture.
The 2.
7V to 5.
5V input voltage range makes the WD1012EA ideally suited for single Li-Ion battery-powered applications.
Supply current with no load is 22ȝA, dropping to 1ȝA in shutdown.
PWM (Pulse Width Modulation) operation provides very low output ripple voltage for noise sensitive applications.
100% duty cycle capability provides low dropout operation, extending battery life in portable systems.
The switching frequency is internally set at 1.
5MHz, allowing the use of tiny surf...
