5V/12V Synchronous-Rectified Buck Controller

uP9305

Features

General Description

The uP9305 is a compact synchronous-rectified buck ꢀ Operates from 5V or 12V Supply Voltage

controller specifically designed to operate from 5V or 12V

supply voltage and to deliver high quality output voltage

as low as 0.6V for uP9305S/W (linear OCP).

ꢁ

3.3V to 12V V_INInput Range

V_REFwith 1.0% Accuracy:

uP9305S/W: 0.6V V_REF

uP9305T/Q: 0.8V V_REF

The uP9305 adopts constant frequency, voltage mode

control scheme, featuring easy-to-use, low external

component count, and fast transient response. Fixed

300kHz operation provides an optimal level of integration

to reduce size and cost of the power supply.

ꢀ Stand Alone Mode Operation

ꢀ Simple Single-Loop Control Design

ꢁ

Voltage-Mode PWM Control

Fast Transient Response

This controller integrates internal 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.

Fixed 300kHz Switching Frequency

ꢀ High-Bandwidth Error Amplifier

0% to 90% Duty Cycle

ꢀ Lossless, Adjuatable Over Current Protection

Other features include internal soft start, over/under

voltage protection, over current protection and shutdown

function. With aforementioned functions, this part provides

customers a compact, high efficiency, well-protected and

cost-effective solutions. This part is available in PSOP-8L

package.
