1 / 12 page  - 1 - TS33001/2 Version 1.3 Specifications subject to change WWW.TRIUNESYSTEMS.COM Copyright © 2012, Triune Systems, LLC DESCRIPTION FEATURES TYPICAL APPLICATION VOUT 10uF 0.47uH Fixed Output EN VSW VCC FB VOUT Sense 22uF VCC EN PG PG 10 kohm (optional) VCC or VOUT nLP nLP VOUT 10uF 0.47uH Adjustable Output EN VSW VCC FB VOUT Sense 22uF VCC EN PG PG RTOP RBOT 10 kohm (optional) VCC or VOUT nLP nLP The TS33001 (1A) and TS33002 (2A) are DC/DC synchronous switching regulators with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 5MHz enables the use of extremely small filter components, resulting in smaller board space and reduced BOM costs. When the input current is greater than approximately 50mA, the TS33001/2 utilizes PWM voltage mode feedback with input voltage feed-forward to provide a wide input voltage range without the need for external compensation. For the Fixed Output option, when the input current is less than 50mA, the device uses a PFM mode to provide increased efficiency at light loads. The cross over between PFM mode and PWM is automatic and has hysteresis to prevent oscillation between the modes. Additionally, the nLP mode pin can be used to force the device into PWM mode to reduce the output ripple, if needed (Fixed Output only). The TS33001/2 integrates a wide range of protection circuitry; including input supply under-voltage lockout, output under-voltage, output over-voltage, soft start, high side FET and low side FET current limits, and thermal shutdown. High Efficiency Synchronous 1A/2A DC/DC Buck Converter, 5Mhz Fixed Output option has automatic low power PFM mode for reduced quiescent current at light loads 5MHz +/- 10% fixed switching frequency Adjustable version output voltage range: 0.6V to 5V with +/- 1.5% reference across temperature Fixed output voltages: 0.8V, 0.9V, 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V with +/- 2% output tolerance Input voltage range: 2.5V to 5.5V (6.0V Abs Max) Voltage mode PWM control with input voltage feed- forward compensation Voltage supervisor for VOUT reported at the PG pin Input supply under voltage lockout Soft start for controlled startup with no overshoot Full protection for over-current, over-temperature, and VOUT overvoltage Less than 100nA in shutdown mode Multiple enable pins for flexible system sequencing Low external component count Junction operating temperature -40C to 125C Packaged in a 16 pin QFN (3x3) APPLICATIONS Point of load Systems with deep submicron ASICs/FPGAs Set-top box Communications equipment Portable and handheld equipment |
