P1886
Description
UTC P1886 consists of 3A step-down switching regulator control which includes a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc with PWM. UTC P1886 can provide low-ripple power, high efficiency, and excellent transient characteristics and an enable function, an over current protect function and a short circuit protect function are built inside, so the operation frequency will be reduced from 300KHz to 30KHz when OCP or SCP happens.
Key Features
- Soft-start, Current Limit, Enable function * Thermal Shutdown function * Built-in internal SW P-channel MOS * Input voltage: 4V to 23V. * Output voltage: 0.8V to VCC. * Duty ratio: 0% to 100% PWM control * Oscillation frequency: 300KHz typ.
