Summit Microelectronics Intros SMB110/SMB113 PPM ICs
Summit Microelectronics Inc. (San Jose, CA), a supplier of programmable, mixed-signal, power management platform solutions, announced two new devices in a growing family of programmable power manager (PPM) integrated circuits (ICs), the SMB110 and SMB113, which can digitally program the entire multiple output power supply and associated power management functions with a few clicks of a mouse.
The SMB110 and SMB113 integrate precise power delivery and power control in a single device. The five-channel SMB110 and four-channel SMB113 PPM ICs are optimized for complex consumer electronics applications such as digital cameras/camcorders, DVD/MP3 portable media players/recorders, global positioning receivers, personal digital assistants, LCD/TFT TV's/monitors, digital set-top boxes and digital video recorders as well as 3G "smart" mobile phones.
The SMB110 comprises a total of five channels of power conversion: two pulse-width modulated (PWM) dc-dc step-down (buck) converters, one PWM dc-dc step-up (boost) converter, one PWM dc-dc inverting step-up/down (buck/boost) converter, and one low-dropout linear regulator. The SMB113 offers four identical channels of PWM dc-dc step-down (buck) converters. The PWM channels on both devices are digitally programmable for output characteristics and monitoring, including voltage output levels to ±0.5% accuracy.
The SMB110 and SMB113 PPM devices operate directly from +2.7 V to +6.0 V input, making them suited for one-cell, lithium-ion battery applications. Higher-input voltages (two-cell lithium-ion or +12 V) can be accommodated in many cases with simple applications configuration. The operating temperature range is +0 °C to +70 °C and packaging is the 5 mm x 5 mm, 32-pad QFN-32 that is lead-free and RoHS-standard compliant.
Available now in production quantities, the SMB110 and SMB113 are both priced at $2.60 each in quantities of 1,000 units.
