Semtech TS30042

High Efficiency 1A/2A Current-Mode Synchronous Buck Converter, 1MHz

Overview

TopologyBuck Converter
Input voltage4.5-40 V
Output 15 V / 2 A
IC revision2.2

Description

The TS30041 (1A) and TS30042 (2A) are DC/DC synchronous switching regulators with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1MHz enables the use of small ! lter components resulting in minimal board space and reduced BOM costs. The TS30041/42 utilizes current mode feedback in normal regulation PWM mode. When the regulator is placed in standby (EN is low), the device draws less than 10uA quiescent current. The TS30041/42 integrates a wide range of protection circuitry including input supply under-voltage lockout, output voltage soft start, current limit, and thermal shutdown. The TS30041/42 includes supervisory reporting through the PG (Power Good) open drain output to interface other components in the system.

Features

  • Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V with +/- 2% output tolerance
  • Adjustable version output voltage range: 0.9V to (VCC - 1V) with +/- 1.5% reference
  • Wide input voltage range: 4.5V to 40V (42V Abs Max)
  • 1MHz +/- 10% ! xed switching frequency
  • Continuous output current: 1A (TS30041), 2A (TS30042)
  • High e" ciency up to 95%
  • Current mode PWM control with PFM mode for improved light load e" ciency
  • Voltage supervisor for VOUT reported at the Power Good (PG) pin
  • Input supply under voltage lockout
  • Soft start for controlled startup with no overshoot
  • Full protection for over-current, over-temperature, and VOUT over-voltage
  • SYNC function on EN/SYNC pin to control switching frequency
  • Less than 10uA in standby mode
  • Low external component count

Typical applications

  • On-card switching regulators/ Industrial power supplies
  • Set-top box, DVD, LCD, LED supply
