150mA Buck Converter - SilTerra 0.18um BCD

Overview

This block is a 150mA, synchronous step-down integrated buck DC-DC converter IP core designed for SilTerra D18V (0.18μm BCD).

The converter compensation and rectifier switches are integrated. It operates in PWM (current control mode) for heavy loads and has a PFM mode for light loads, improving its efficiency.

It also features power good indicator, over-current protection (at start-up and cycle-by-cycle), and the option to have an external reference.

Key Features

  • PWM, PFM and forced PWM modes
  • Excellent line transient response
  • High Efficiency (around 90%)
  • Output load up to 150mA
  • Input voltage: 2.5– 5.5V
  • Adjustable output voltage (1.3– 3.3V)
  • Output voltage accuracy: ±5%
  • 3MHz switching frequency
  • Core area: 760µm ×845µm (0.47mm2)
