5V/12V Synchronous-Rectified Buck Controller

Features

General Description

The uP1514R is a compact synchronous-rectified buck

controller specifically designed to operate from 5V or 12V

supply voltage and to deliver high quality output voltage

as low as 0.8V. This 8-pin device operates at fixed 300kHz

frequency and provides an optimal level of integration to

reduce size and cost of the power supply.

Operate from 5V or 12V Supply Voltage

3.3V to 12V V_INInput Range

0.8V V_REFwith 1.0% Accuracy

Output Range from V_REFto 80% of V_IN

Simple Voltage-Mode PWM Control Design

The uP1514R integrates MOSFET drivers that support

12V+12V bootstrapped voltage for high efficiency power

conversion. The bootstrap diode is built-in to simplify the

circuit design and minimize external part count.

300 kHz Fixed Frequency Oscillator

Internal Compensation

Fast Transient Response

0% to 80% Duty Cycle

Besides, an OCP/EN is used for chip disable and

continuous setting of over current protection level.

Internal Bootstrapped Gate Drivers

Other features include under voltage lockout (UVLO),

internal softstart, under voltage protection, over voltage

protection. With aforementioned functions, this part

provides customers a compact, high efficiency, well-

protected and cost-effective solutions. This part is available

in SOP - 8L or PSOP - 8L packages.
