DESCRIPTION

The UTC UD100241 is an easy-to-use asynchronous step-down

converter, which integrated low on-resistance high-side MOSFET to

achieve better efficiency.

The UD100241 can deliver 2.4A maximum output current with

adjustable current limit, the startup current is as 2.5μA typically, easy

to be used in low power design. The UD100241 employs variable

off-time control mode with frequency jitter to achieve easy EMI

design.

The UD100241 employs Built-in loop compensation network, so

extra external compensation component is not needed, which

minimized the solution BOM list. The UD100241 innovated FB2

design, make the high side buck structure better. The transient and

no-load performance are optimized, meanwhile the system solution

size is minimized.
