The AP2014 controller IC is designed to provide a
low cost synchronous Buck regulator for on-board
DC to DC converter applications. With the migration
of today’s ASIC products requiring low supply
voltages such as 1.8V and lower, together with
currents in excess of 3A, traditional linear regulators
are simply too lossy to be used when input supply is
5V or even in some cases with 3.3V input supply.
The AP2014 together with dual N-channel
MOSFETs such as AF9410, provide a low cost
solution for such applications. This device features
an internal 200KHz oscillator (400KHz for "A"
version), under-voltage lockout for both Vcc and Vc
supplies, an external programmable soft-start
function as well as output under-voltage detection
that latches off the device when an output short is detected.
