EUP2621 620kHz/1.
25MHz Step-up DC/DC Converter DESCRIPTION The EUP2621 is a high performance current mode, PWM step-up converter with pin selectable operating frequency.
With an internal 1.
6A, 200m£[ MOSFET, it can generate 12V at up to 400mA output current from a 5V supply.
The selectable 620kHz and 1.
25MHz allows smaller inductors and faster transient response.
An external compensation pin gives the user greater flexibility in setting loop compensation allowing the use of low ESR Ceramic output capacitors.
Soft-start is controlled with an external capacitor, which determines the input current ramp rate during start-up.
When shut down, it draws¡Õ 10µA of current and can operate down to 2.
5V...
