RT9232APS
RT9232APS - Brand New RICHTEK IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The RT9232A is a single-phase synchronous buck PWM DC-DC converter controller
designed to drive two N-Channel MOSFET. It provides a highly accurate,
programmable output voltage precisely regulated to low voltage requirement
with an internal 0.8V ± 1% reference. The RT9232A uses an external
compensated, single
feedback loop voltage mode PWM control for fast transient response. An
oscillator with Programmable frequency (50kHz to 800kHz) reduces the external
inductor and capacitor component size for saving PCB board area.
